Line 12:
The list is to be in (ascending) order of the (chemical) element's atomic number:
''hydrogen helium lithium beryllium boron carbon nitrogen oxygen fluorine neon sodium aluminum silicon ...''
... up to the last known (named) chemical element (at this time).
Do not include any of the "unnamed" chemical element names such as:
''ununennium unquadnilium triunhexium penthextrium penthexpentium septhexunium octenntrium ennennbium''
Line 28:
if a computer programming language has more restrictive limitations or standards.
Also mention what column the programming statements can start in if ''not''
in column one.
Line 57:
:* Try to use the most idiomatic approach(es) in creating the final list.
:* Use continuation if possible, and/or show alternatives (possibly using concatenation).
:* Use a program comment to explain what the continuation character is if
:* The program should contain a variable that has the date of the last update/revision.
:* The program, when run, should display with verbiage:

There is no need for continuation codes, as the language interprets a contiguous data block as a single entity, whether you intended it to be or not. If you had two consecutive strings embedded in the code and you forgot the null terminator on the first one, trying to print just the first string would print both. For example:
<syntaxhighlight lang="6502asm">HelloString:
db "Hello World" ;no null terminator
GoodbyeString:
db "Goodbye World!",0
PrintString HelloString ;unimplemented macro.</syntaxhighlight>
The output would be as follows, assuming the <code>PrintString</code> routine uses a null terminator to know when a string ends:
<pre>
Hello WorldGoodbye World!
</pre>
In addition, it makes no difference to the assembler whether each string is on its own line, or each is one after the other on the same line. It's easier to put each on its own line since you can't have a label mid-line.
Since each string is of variable length, it is much easier to make a lookup table of the elements ordered by atomic number, with each element in the lookup table being a pointer to the actual string consisting of that element's name.
<syntaxhighlight lang="6502asm">ElementNull:

Elements:

ElementCount equ (Elements_End-Elements)/2
; a constant value that cannot change at runtime.
; This counts the number of bytes between the two labels, and automatically adjusts when the size of the list changes.
; The division by 2 gets the actual element count since each address is 2 bytes long.</syntaxhighlight>
The required output can be obtained like so:
<syntaxhighlight lang="6502asm">LDA #<RevisionDate ;get the low byte of the address
STA z_L ;store it in z_L, a zero page memory address
LDA #>RevisionDate ;get the high byte
STA z_H ;store it in z_H, the zero page memory address directly after z_L
JSR PrintString ;unimplemented printing routine
JSR NewLine
LDA ElementCount
JSR ConvertHex2BinDec ;converts a hexadecimal value to a trio of BCD digits
JSR PrintBCD ;unimplemented printing routine for numeric values
LDA #$20 ;ASCII for spacebar
JSR PrintChar
LDA #<Finally
STA z_L
LDA #>Finally
STA z_H
JSR PrintString
LDA #$20 ;ASCII for spacebar
JSR PrintChar
LDA ElementCount
ASL A ;multiply by 2, we are indexing into a table of words.
TAX ;use as an offset into the lookup table.
LDA ElementNull,x ;ElementCount doesn't account for zero-indexing so we'll need to load one word behind.
STA z_L
LDA ElementNull+1,x
STA z_H
JSR PrintString</syntaxhighlight>
This routine can be expanded as new elements are discovered, but once the 128th element is discovered it will need to be reprogrammed since you can't offset more than x=255. This is actually a very simple fix, and can be accomplished by splitting the table as such:
<syntaxhighlight lang="6502asm">Elements_Lo:
db <hydrogen,<helium,<lithium,<beryllium,<boron,<carbon,<nitrogen,<oxygen,<fluorine,...
Elements_Hi:
db >hydrogen,>helium,>lithium,>beryllium,>boron,>carbon,>nitrogen,>oxygen,>fluorine,...</syntaxhighlight>
Note that < and > are unary operators that mean "the low byte of" and "the high byte of", respectively. By storing the halves of each pointer in two separate tables, sharing a common index, we can index up to 256 elements rather than 128, without increasing the total data size of the tables.

There is no need for continuation codes, as the language interprets a contiguous data block as a single entity, whether you intended it to be or not. If you had two consecutive strings embedded in the code and you forgot the null terminator on the first one, trying to print just the first string would print both. For example:
<syntaxhighlight lang="68000devpac">HelloString:
DC.B "Hello World" ;no null terminator
GoodbyeString:
DC.B "Goodbye World!",0
EVEN
PrintString HelloString ;unimplemented macro.</syntaxhighlight>
The output would be as follows, assuming the <code>PrintString</code> routine uses a null terminator to know when a string ends:
<pre>
Hello WorldGoodbye World!

In addition, it makes no difference to the assembler whether each string is on its own line, or each is one after the other on the same line. It's easier to put each on its own line since you can't have a label mid-line.
Since each string is of variable length, it is much easier to make a lookup table of the elements ordered by atomic number, with each element in the lookup table being a pointer to the actual string consisting of that element's name.

ElementCount equ (Elements_End-Elements)/4
; a constant value that cannot change at runtime.
; This counts the number of bytes between the two labels, and automatically adjusts when the size of the list changes.
; The division by 4 gets the actual element count since each address is 4 bytes long.</syntaxhighlight>
The required output can be obtained like so:
<syntaxhighlight lang="68000devpac">LEA RevisionDate,A3 ; the printing routine uses A3 as input
JSR PrintString ; unimplemented printing routine
JSR NewLine ; unimplemented new line routine
MOVE.B ElementCount,D0
JSR ConvertHex2BinDec ; converts a hexadecimal value to a trio of BCD digits
JSR PrintBCD ; unimplemented printing routine for numeric values
MOVE.B #' ',D0 ; ASCII for spacebar
JSR PrintChar
LEA Finally,A3
JSR PrintString
MOVE.B #' ',D0 ; ASCII for spacebar
JSR PrintChar
MOVE.W ElementCount,D1
LSL.W #2,D1 ; multiply by 4, we are indexing into a table of longs
LEA NullElement,A2
; load the base of the lookup table into A2. This is the table's "true base"
; since the "ElementCount" constant doesn't account for zero-indexing
MOVEA.L (A2,D1),A3
;dereference the pointer, offsetting by D1. This retrieves the address of the desired element in the list.
JSR PrintString</syntaxhighlight>
This routine can easily be expanded for more elements. With a maximum offset of 16,383, it's unlikely that the table will get too large to properly index anytime soon.

Words (;:) is the sequential machine configured for lexical analysis of j. In many cases, certainly this one, j words look like English words. Words cannot have an inverse because it discards leading and trailing spaces, losing spacing information. The obverse unites the boxed words with a single space separation, the best it can do. Which is just right for this task.

Back-ticks and triple-quotes permit multi-line strings. We first replace all/any cr/lf/tab characters with spaces, then split (by default on a single space), omitting empty elements. You could use spaced_elements = join(elements) to join them back up into a space-separated single string, if that's really what you want, and you could then, like Go, use rfind(' ',spaced_elements) to re-extract the last one.
You could also, like Julia, use get_file_date(command_line()[2]) instead of the hand-written last_updated constant. Phix code is free-format, indent things however you like, there is no specific maximum line length.

{{incorrect|Raku|The task is to have a list of the names of the elements, not their atomic weight and chemical element symbol. <br> Also, the element names are not capitalized.}}
Incorrectly marked incorrect. Enforcing rules that exists only in somebodies head.
{{works with|Rakudo|2020.02}}
Not really sure I understand the point of this task. Seems to be load some list into memory and manipulate it somehow. Exceptionally boring to just read it in and then read it back out again. Perform some more interesting manipulations. Use < > quoting construct for literal string; unlimited (memory limited) characters, spaces don't matter, new-lines don't matter, blank lines don't matter.

This solution uses a "doc string", a chunk of text that the parser eats
verbatim. It starts and ends with #<<<. If started with #<<<", a leading " is
added to the text. The text is then parsed as one [long] line.
The string split method creats a list of items split at white space
(by default). To turn that into one string with one space between each item,
use: elements.concat(" ")
