sub function Lo(number as longint) as byte

Lowest 8 bits (byte) of 

number

, bits

7..0

.

Function returns the lowest byte of 

number

. Function does not interpret bit pat-

terns of 

number

– it merely returns 8 bits as found in register.

This is an “inline” routine; code is generated in the place of the call, so the call
doesn’t count against the nested call limit.

Arguments must be variable of scalar type (i.e. Arithmetic Types and Pointers).

d = 0x1AC30F4 

tmp = Lo(d)  ' Equals 0xF4

sub function Hi(number as longint) as byte

Returns next to the lowest byte of number, bits 8..15.

Function returns next to the lowest byte of 

number

. Function does not interpret

bit patterns of 

number

– it merely returns 8 bits as found in register.

This is an “inline” routine; code is generated in the place of the call, so the call
doesn’t count against the nested call limit.

Arguments must be variable of scalar type (i.e. Arithmetic Types and Pointers).

d = 0x1AC30F4
tmp = Hi(d)  ' Equals 0x30

sub function Higher(number as longint) as byte

Returns next to the highest byte of 

number

, bits 16..23.

Function returns next to the highest byte of 

number

. Function does not interpret

bit patterns of 

number

– it merely returns 8 bits as found in register.

This is an “inline” routine; code is generated in the place of the call, so the call

Arguments must be variable of scalar type (i.e. Arithmetic Types and Pointers).
