The .AZ directive converts ASCII strings and/or expressions to hexadecimal bytes. The last generated byte will be followed by one extra byte with the value of $00 to signal the end of the string. This can be used to signal the end of a character processing loop. Apart from this minor difference the .AZ directive works exactly the same as the .AS directive.

Boundary Sync:

In Version 3 of the SB-Assembler this directive will not perform a boundary sync.


The string parameter is a delimited string. The expression should evaluate to a positive number that is less than 256. The parameter can consist of more than one string and/or expression, which all should be separated from each other by commas.
All generated bytes will have bit b7=0 if the first character of the parameter is not a - sign, this is called positive ASCII. If the first character of the parameter is a - sign all generated bytes will have b7=1 except the trailing $00 byte, this is called negative ASCII.
The delimiters may not enclose an empty string. They should enclose at least one character.
