There are probably more ways do write a message in the system log – “Write to Operator” from a Rexx script.
This is a very straightforward one I found some time ago somewhere on the Interweb.
/* rexx */ trace r call syscalls 'ON' address syscall path='/dev/console' 'open' path O_wronly 666 if retval=-1 then do say 'file not opened, error codes' errno errnojr return end fd=retval rec= 'This is my message text to appear in the system log.' || esc_n 'write' fd 'rec' length(rec) if retval=-1 then say 'record not written, error codes' errno errnojr 'close' fd
Have more solutions? Or remarks? Please let me know below.
