Re: Function to find the greatest or smallest value

You could also place the values in an array, sort it, and pick the first
for min and last for max (assuming the array size is the same as the number
of values you want the max of).

e.g, if you wanted the max of {-1, 16, 25}, and the array was actually four
elements long, you would have to sort only the first three elements, and
select element 3 after the sort. Otherwise, if you sorted the whole array,
the sort would result in

-1
0
16
25

whereas sorting (1, 16, 25} would result in

0
1
16
25


and sorting (-1, -16, -25} would result in

-25
-16
-1
0


Use BIF %SORTA() to sort only the number of values you want the min and max
of, and then
array(1) will be the min and array (numberOfvalues) will be the max.

If you have not searched the manuals (i.e. the Index of the RPG Reference),
you should have first, but no, you have to write your own.

If the values come from a PF (table), use SQL and the MIN/MAX-functions.

Given 2 or more values, is there a BIF or something in RPG that will

return the highest of those values?
