$POINT

$POINT returns the fpoint value (as an integer) of a FIXED expression.

fixed-expression

fixed-expression cannot call a routine and cannot be an assignment expression.

$PROCADDR

$PROCADDR converts an INT(32) value to a PROCADDR address.

pTAL privileged procedure No

Can be executed only by privileged procedures No

Sets condition code No

Sets $CARRY No

Sets $OVERFLOW No

Example 15-74. $POINT Routine

FIXED(3) result;

FIXED(3) a;

FIXED(3) b;

result := $SCALE (a, $POINT (b)) / b;

! Return fpoint of FIXED expression & scale value by that factor
