AW: Function to find the greatest or smallest value

["Birgitta Hauser" <Hauser@xxxxxxxxxxxxxxx>]

Hi,

The SQL scalar functions MIN() and MAX() can also be used within RPG to find
the highest or lowest value from a list of values:

Example:
   Exec SQL Set :MyMinVal = Min(1, -17, 35, 4, -2, 0);
   Exec SQL Set :MyMinDate = Min(Date('2009-01-03'), Date('2009-02-18'),
:Date('2008-12-31'));
   Exec SQL Set :MyMaxChar = Max('ABC', 'A', ' XY', 'A34579');
   Exec SQL Set :MyMaxVal = Max(:HstVar1, :HstVar2, :HostVar3, :HostVar4);

Mit freundlichen Grüßen / Best regards

Birgitta Hauser

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.
