Does a logical AND between the bits of two data items.
Syntax:
call "CBL_AND" using source
target
by value length
Parameters:
|
Using call prototype (see
Key)

Picture
|
source
|
cblt-x1-compx
|
Any data item.
|
target
|
cblt-x1-compx
|
Any data item.
|
length
|
cblt-os-size
|
Numeric literal,
pic x(4) comp-5
or
pic x(8) comp-5 (64-bit native programs only)

On Entry:
source
|
One of the data items to AND.
|
target
|
The other data item to AND.
|
length
|
The number of bytes of
source and
target to AND. Positions in
target beyond this are unchanged.

Comments:
The routine starts at the left-hand end of source and target and ANDs the bits together, storing the result in target. The truth table for this is:
