HFZWTO command
The HFZWTO command is used to write a message to the MVS™ console. This command can, for example, be used instead of the REXX SAY command whenever tracing is not active (HFZTRACE DDname not allocated).
New-line characters (X'15') in the message text can be used to split long messages into multiple WTOs. Any other non-printable characters are changed to periods.
Return codes
The HFZWTO command always completes with RC=0.
Example
To avoid possible confusion, it is recommended that any WTO messages that are issued do not
include a message ID that could be mistaken for one of the formal messages issued by Z Abend Investigator. If you want to prefix message IDs with
HFZ
, then you might add an extra character to
eliminate the chance of matching a Z Abend Investigator
message, for example, HFZX
followed by a
number.
