>>-.---.-.----.—NULL-ESCAPE--->< +-/-+ +-NO-+
Some systems allowed you to embed control characters in the source as if they were escaped by a null character. Use NONULL-ESCAPE if you embed single 0x00 characters in literals in your source code. This replaces the previous option of COBSW=-N.
Alternatively, use x"00" syntax to represent null characters in your literals or z" literal syntax to end a literal in a null character.
