ON...PROC

This command is used to force a call to subroutine when a specific expression is calculated. The choice is done against several positions, and it depends on what value is held by the expression at the time it is spotted.

To work properly, the expression must have a value from 1 up to the number of the highest possible destination. If the expression has a value of 0 or greater than the highest possibile destination, no call will be performed.
