pTAL Reference Manual (G06.24+, H06.09+, J06.03+)

The quotient or remainder of an FIXED dividend and an INT(32) divisor is an INT(32) quotient
in the range 0 to 232-1.
$OVERFLOW (page 335) returns false after an unsigned division or remainder operator unless
either of the following is true:
◦ The divisor is 0
◦ The quotient is greater than 216-1 for an INT quotient, 232-1 for an INT(32)
Comparing Addresses
pTAL rules for comparing address types are more restrictive than the rules for comparing nonaddress
types.

Extended Addresses
The following rules apply when you compare extended addresses (EXTADDRs, EXT32ADDRs, and
EXT64ADDRs):
• Use signed relational operators to compare extended addresses. Unsigned operators are not
valid.
• If you compare an EXTADDR or EXT32ADDR address to a constant, the constant must be a
32-bit integer.
• If you compare an EXT64ADDR address to a constant, the constant must be of type FIXED.
• If you compare two different sized extended addresses, the smaller address is implicitly cast
to the larger address and then compared.
NOTE: The address types, EXT32ADDR, EXT64ADDR, PROC32ADDR, and PROC64ADDR are
available in the 64-bit addressing functionality added to the EpTAL compiler starting with SPR
T0561H01^AAP. For more information, see Appendix E, “64-bit Addressing Functionality”
(page 531).
