MODULO operator

Determines the remainder after division.

Syntax
expression MODULO base 
expression
An integer expression.
base
A positive integer expression that is the modulo base. For example, angles measured in degrees use a base of 360 for modulo arithmetic. 372 MODULO 360 is 12.
Example

This procedure determines the number of trucks required to ship a given quantity of material, and how much material is left over from a less than full truck load:
r-modulo.p
REPEAT:
  SET qty-avail AS INTEGER LABEL "Qty. Avail.".
  SET std-cap AS INTEGER
  LABEL "Std. Truck Capacity".
  DISPLAY TRUNCATE(qty-avail / std-cap,0)
    FORMAT ">,>>9" LABEL "# Full Loads"
    qty-avail MODULO std-cap LABEL "Qty. Left".
END. 
Note

The expression must be greater than 0 for MODULO to return a correct value.
