01  [/CREATE-FILE FILE-NAME=monitor-file
      [,SUPPORT=*PUBLIC-DISK(SPACE=*RELATIVE(PRIMARY-ALLOCATION=primary - 
       ,SECONDARY-ALLOCATION=secondary)) or
       ,SUPPORT=*PRIVATE-DISK(VOLUME=priv-vsn,DEVICE-TYPE=device[,SPACE=...])]]
    [/ADD-FILE-LINK LINK-NAME=TR,FILE-NAME=monitor-file,ACCESS-METHOD=*SAM]
02  /START-UDS-MONITOR
03  "udsmon statements for starting"
04 EM, DUE
05 "udsmon commands during execution"
06 EM, DUE

Explanation

01	If the monitor file is to be set up explicitly, the CREATE-FILE command must be used for this purpose. In this case specifying :catid: is permitted in accordance with BS2000 conventions (see section “Using pubsets in UDS/SQL”).
02	The monitor is started.
04/06	An interrupt during monitor execution is initiated by means of EM, DUE.
07	The monitor is terminated.

After a program interrupt, due to [K2] for example, the INFORM-PROGRAM command is required in order to resume operation.

In batch mode, an invalid UDSMON statement causes the monitor start to be terminated. An error message is output to SYSOUT.
