Stack Transformation: (a(2), b -- a(2)>>b)

Location: Near

Registers Affected: None

Example:

This example shifts 16 right 2.

pushs #d’2 ; (d’2)

pushd #d’16 ; (d’16, 0, d’2)

call _r_shift16 ; (d’4, 0)

_r_shift16s (Right Shift Signed, 16 Bit)

This function shifts a signed 16-bit integer right. b must be in the range 0..7.

Stack Transformation: (a(2), b -- a(2)>>b)

Location: Near

Registers Affected: None

Example:

This example shifts -16 right 2.

pushs #d’2 ; (d’2)

pushd #-d’16 ; (-d’16, -d’1, d’2)

call _r_shift16s ; (-d’4, -d’1)

_r_shift8 (Right Shift, 8 Bit)

This function shifts an unsigned integer right. b must be in the range 0..7.

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

Location: Near

Registers Affected: None

Example:

This example shifts 16 right 2.

pushs #d’2 ; (d’2)

push #d’16 ; (d’16, d’2)

call _r_shift8 ; (d’4)

_r_shift8_<n> (Right Shift <n>, 8 Bit)

This function shifts an unsigned integer right. n must be in the range 3..7.
