FXDVCK - set quotient to return for a divide check.

Usage:

call fxdvck(float [, int])

Where:

float

is the double-precision value that is to be used after a floating point divide check.

int

is the integer that is to be used after an integer divide check.

Description:

FXDVCK allows the program to specify what value should be returned as the quotient from any subsequent divide check faults. If FXDVCK is not called, a floating divide check will return the largest floating point value, and an integer divide check will return the dividend.

If a divide check fault occurs while using the intrinsic function MOD, the result is undefined even if FXDVCK has been used.
