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?
Ooooops!
2 dtot,
3 l_max fixed (9,1) init (0),
3 l_min fixed (9,1) init (9999.9),
3 t_max fixed (9) init (0),
3 t_min fixed (9) init (5999),
3 v_max fixed (13,9) init (0),
3 v_min fixed (13,9) init (9999.999999999),
And the variables are part of the same (huge) "lift_work" automatic structure.
