Line 4:
: Several programming examples are treating the input as characters instead of tokens, and this is working because there are no multi-digit numbers, and no numbers that contain a decimal point, and no numbers that are expressed in exponential notation (such as 3E27), and no numbers that have a leading sign, and no multi-character operands (such as '''**'''), etc. Should those programs be considered incorrect? (Just because they come up with the correct answer, doesn't make it correct. Hurrumph!) -- [[User:Gerard Schildberger|Gerard Schildberger]] 23:56, 14 December 2012 (UTC)
::The Fortran example contains the remark that dealing only with single-digit integers enables a simple scan, while a fuller multi-digit integer (or further, floating-point with exponent part) requires much more code which would obscure the presumed objective of exemplifying the parsing of RPN itself. I have a function EATREAL that takes 120 lines, while the task is achieved in less than fifty. As for revealing the state at each step, two statements: a WRITE and a FORMAT suffice.

:::::: I am fine waiting for some time. I created that Village Pump page in the hopes of soliciting feedback, but none has yet been given. What other steps should I take to get a wider chorus of voices chiming? Thanks for your feedback and guidance! --[[User:Abathologist|Abathologist]] ([[User talk:Abathologist|talk]]) 03:09, 3 October 2016 (UTC)
::::::: Yes. Thank you. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 04:03, 3 October 2016 (UTC)
::::Whilst the actual logging code is probably mundane, it does show how the algorithm works. If there was a vote, I'd favour keeping this particular task as it currently is. --[[User:Tigerofdarkness|Tigerofdarkness]] ([[User talk:Tigerofdarkness|talk]]) 19:12, 3 October 2016 (UTC)
