Character set

All characters are allowed for messages except the following:

• X'4E' (+), which is the end-of-message control character
• X'6E' (>), which is the start-of-message control character.

z/TPF system code unconditionally translates these two characters to X'4B' (.). Control program (CP) user exit WTOP is provided for you to customize your output. For more information about this user exit, see Control program user exits and the code comments.
