WTOPC Message Translation

User exit routine UCCWTOP is invoked from control program (CP) copy member CEDI to allow you to translate individual characters in output message text. CEDI normally translates the plus sign (+) and greater than sign (>) into periods (.). UCCWTOP allows you to translate the plus sign (+) and greater than sign (>) into characters other than periods (.) before CEDI translates them.

General Conditions at Entry

The registers at entry to UCCWTOP are:

R5
The number of bytes, from 1 to 256, to be translated.

R7
Pointer to the first byte of text to be translated.

R8
Pointer to the primary terminal address for this message.

R11-R15
See User Exit Routines - Common Entry Conditions.

System Conditions at Entry

System state
Supervisor

System mask
Masked

Protect key
0

Address space
SVM.

Programming Considerations at Entry

  1. This routine can be called several times for a single message depending on the length of the message. Therefore, the message header may not be part of the message text to be translated.
  2. See User Exit Routines - Common Programming Considerations for other considerations.
