pc doesn't allow an ``others'' clause in outputs

I hate to disillusion you, but by your definition, the language pc compiles
wasn't Pascal before!  There are at least a dozen major deviations from
Nicklaus & Wirth spelled out in the pc manual, plus a list of non-standard
predefined functions 2 pages long.  Most of the deviations don't change the
syntax of the language as the others clause does, but they sure have the
same effect on portability!  I think the real question is writability.
Most compiler writers found this feature important enough to break the
standard.

Don Knuth commented on this topic.  His TeX program is written in a
language preprocessed into Pascal.  When asked why he didn't have his
preprocessor translate "others" into code obeying Nicklaus & Wirth, he said
"I thought it would be better to have someone fix the compilers."

Does anyone know whether the ANSI and ISO standards include an "others"?
