Dear all,
A few days ago I posted the following to <news://comp.lang.pl1>,
addressed specifically to Peter Elderon:
"And the corresponding PL/I source is ?"
Note for what follows: PL/I has a truckload of builtin functions to
work with dates and times, but none of them seem to cater for times in
just minutes, as opposed to seconds or even micro-seconds.
The reason for asking the question? The two statements in question
min_max_line.t_max_hh = dtot.t_max / 60;
min_max_line.t_max_mm = mod(dtot.t_max, 60);
copy a time (in minutes, in packed format) to a print-line, in hh:mm
format, which means splitting up said time into hh & mm by a division
and a remainder, which, given that times can not be negative, can use
PL/I's "MOD(ulo)" builtin function although obviously(!) that is not
the best thing to do, as modulo and remainder may not have the same
sign, given that modulo is defined as
Sorry if it's obvious from the posting - but I was wondering what the
type of "t_max" might be and if it (well "dtot") happens to be BASED?
