$UDIVREM16

$UDIVREM16 divides an INT(32) dividend by an INT divisor to produce an INT

quotient and INT remainder.

dividend input

INT(32):value

divisor input

sINT:value

quotient output

sINT:variable

remainder output

sINT:variable

The compiler checks the following conditions during compilation:

•

If the value of divisor is a constant value of zero, the compiler reports an error

that division by zero is not valid:

$UDIVREM16(dividend, 2 / 2 - 1, quot, rem); ! Report error

Example 15-89. $UDBL Routine

INT a16 := -1;s

INT(32) a32;

a32 := $UDBL (a16); ! Return 65535D

pTAL privileged procedure No

Can be executed only by privileged procedures No

Sets condition code No

Sets $CARRY No

Sets $OVERFLOW Yes, if the divisor is 0 or the

quotient is too large
