$MORSE.REX
The following is the $MORSE.REX (REXX) program.
This program supports the International Morse code as well as
the USA Morse code (the later being primarily used by the
North American Railroads).
Some translation is done for unsupported characters such as braces { }, brackets [ ] and the like.
This REXX program normally shows Morse code words one word to a line before sounding.
This REXX programs only works for Regina and PC/REXX, but other REXXes (specifically R4 and ROO) will only display the Morse code, but not sound it.
The help for the $MORSE.REX REXX program is included
here ──► $MORSE.HEL.
The $MORSE.REX REXX program makes use of LINESIZE REXX
program (or BIF) which is used to determine the screen width (or linesize) of the
terminal (console).
The LINESIZE.REX REXX program is included here ──► LINESIZE.REX.
The $MORSE.REX REXX program makes use of $T.REX REXX
program which is used to display text and/or write the text to a file.
The $T.REX REXX program is included here ──► $T.REX.
The $T.REX REXX program makes use of DELAY.REX REXX
program which is used to delay (sleep) a specified amount time.
The DELAY.REX REXX program is included here ──► DELAY.REX.
The $MORSE.REX REXX program makes use of $ERR.REX REXX
program which is used to display error messages (via $T.REX).
The $ERR.REX REXX program is included here ──► $ERR.REX.
The $MORSE.REX REXX program makes use of SOUND.REX REXX
program which is used to express sound (via the internal speaker).
The SOUND.REX REXX program is included here ──► SOUND.REX.
Some older REXXes don't have a changestr BIF, so one is included
here ──► CHANGESTR.REX.
