$StrAnd

Bit-wise AND two strings

Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $StrAnd function is BitAndString.

This function performs a bit-wise AND of two strings.

The $StrAnd function accepts three arguments and returns a string result that is the bit-wise AND of the first two arguments, the shorter being padded with as many copies of the third argument as are required to make the string lengths equal.

Syntax

%str = $StrAnd(string1, string2, [pad])

Syntax terms

%str	The bit-wise AND of string1 and string2.
string1	An arbitrary string.
string2	Another arbitrary string.
pad	An arbitrary string that is appended to the shorter of the first two strings and replicated as many times as required to make the strings of equal length. If this value is not specified or is null, it defaults to a single null byte (X'00').

Examples

1. This code fragment would set %junk to X'010221000000':

   %X = $X2C('112233445566') %Y = $X2C('654321') %junk = $StrAnd(%X, %Y)

2. These statements would set %junk to X'000000444444':

   %X = $X2C('112233445566') %junk = $StrAnd(%X, , $X2C('CC'))

3. This code fragment would set %junk to X'112233005500':

   %X = $X2C('112233445566') %Y = $X2C('1122') %Z = $X2C('FF00') %junk = $StrAnd(%X, %Y, %Z)
