Stack Transformation: (a, b -- a<b)

Location: Near

Registers Affected: None

Example:

This example determines if d’10 < d’20.

push #d’20 ; (d’20)

push #d’10 ; (d’10, d’20)

call _less8 ; (1)

_less8s (Less Than Signed, 8 Bit)

This function returns a < b, where a and b are signed.

Stack Transformation: (a, b -- a<b)

Location: Near

Registers Affected: None

Example:

This example determines if d’10 < -d’10.

push #@lb(-d’10) ; (-d’10)

push #d’10 ; (d’10, -d’10)

call _less8s ; (0)

_log16 (Logical Value, 16 Bit)

This function returns the logical representation of a 16-bit value. If the variable

is non-zero, true is returned, otherwise false.

Stack Transformation: (a(2) – a?1:0)

Location: Near

Registers Affected: None

Example:

This example returns the logical value for 5.

pushd #d’5 ; (d’5, 0)

call _log16 ; (1)

_log8 (Logical Value, 8 Bit)

This function returns the logical representation of a value. If the variable is non-

zero, true is returned, otherwise false.
