You don't need a routine. Given two numbers, a and b, the statement
c = a > b
gives the max of the two, while
c = a < b
gives the min.

Sure!
IDL> a = 40
IDL> b = 45
IDL> print, min([a,b]), max([a,b])

For two or more separate numbers, you can use < and > for min/max
Examples:
> print, 1< 2
1
> print, 22 < 1.5 < 3 < 6 < 7
1.5
> temp = 1 > 3 > 2
> print, temp
3
There's more under "Miminum Operator" and "Maximum Operator"
in the IDL manuals.
Hope this helps
Tim
