!PHLOG() |

|
The !PHLOG() subroutine returns the name of the log record for a running phantom process.
Format
CALL !PHLOG(name, userno)
where
A phantom process creates a log record in the $COMO file containing any output that would have gone to the screen if the command had been run in an interactive session. The name of this log record is PHn_date_time where n is the QM user number of the phantom process and date_time is the date/time at which the phantom started in the form ddmmyy_hhmmss.
The !PHLOG() subroutine allows a process to determine the name of the log record for a phantom so long as the phantom is still active.
If the phantom is started using the NO.LOG option of the PHANTOM command, name is returned as a null string.
Because the !PHLOG() subroutine returns the log name via its first argument, it can be declared as a function as in the example below.
Example
DEFFUN PHLOG(U) CALLING "!PHLOG" EXECUTE "PHANTOM OVERNIGHT.REPORT" SETTING UNO DISPLAY "Log is " : PHLOG(UNO)
Note how the SETTING clause of the EXECUTE statement is used to capture the @SYSTEM.RETURN.CODE value from the PHANTOM command. Simply using @SYSTEM.RETURN.CODE as the argument to PHLOG() would not work as this would be the return status of the EXECUTE operation, not the executed command.
