I run this rexx Code but ITS cannot run and it seems that cant read ISFLINE in syslog.

/* REXX */
RC = ISFCALLS('ON')
If RC <> 0 Then Do
Say "Error in enabling ISFCALLS. RC:" RC
Exit
End

ADDRESS SDSF "ISFLOG READ TYPE(SYSLOG)"
If ISFLINE.0 = 0 Then
Say "No lines read or access error."
Else Do
Do IX = 1 To ISFLINE.0 /* PROCESS THE RETURNED VARIABLES */
Say ISFLINE.IX
End
End

RC = ISFCALLS('OFF')
If RC <> 0 Then
Say "Error in disabling ISFCALLS. RC:" RC

After execute:

No lines read or access error.

Please, use the code tag button when presenting code/data to the forum.

The logic successfully reads the log here. Maybe you have a security issue to fix on your end.

Maybe after
Code:
ADDRESS SDSF "ISFLOG READ TYPE(SYSLOG)"

insert lines to check the ISF messages
e.g.
Code:
do ix=1 to isfmsg2.0
  say isfmsg2.ix
end


The messages might give a clue.

Garry.
