This example acquires the semaphore, then modifies a global variable, then
releases the semaphore.

_l_shift16 (Left Shift, 16 Bit)
This function shifts an unsigned 16-bit integer left. b must be in the range 0..7.
Stack Transformation: (a(2), b -- a(2)<Location: Near
Registers Affected: None
Example:
This example shifts 16 left 2.
pushs #d’2 ; (d’2)
pushd #d’16 ; (d’16, 0, d’2)
call _l_shift16 ; (d’64, 0)
_l_shift16s (Left Shift Signed, 16 Bit)
This function shifts a signed 16-bit integer left. b must be in the range 0..7.
Stack Transformation: (a(2), b -- a(2)<Location: Near
Registers Affected: None
Example:
This example shifts 16 left 2.
pushs #d’2 ; (d’2)
pushd #d’16 ; (d’16, 0, d’2)
call _l_shift16s ; (d’64, 0)
_l_shift8 (Left Shift, 8 Bit)
This function shifts an unsigned integer left. b must be in the range 0..7.
Stack Transformation: (a, b -- a<Location: Near
