To invoke the ATBTRACE exec using IKJEFT01 (to run the exec in the TSO/E background), specify the following on the JCL EXEC statement:

1. IKJEFT01 on the PGM parameter, and
2. ATBTRACE and its parameters either:
   • On the PARM parameter, or
   • Through explicit or implicit use of the EXEC command in the input stream.

For example, the following contains JCL to submit an ATBTRACE STOP request:

//JOEA    JOB MSGLEVEL=(1,1)
//*
//* EXAMPLE OF STOPPING A TRACE BY INVOKING
//* ATBTRACE IN BATCH USING IKJEFT01 WHICH
//* WILL BRING UP A TSO/E ENVIRONMENT VIA
//* THE TMP
//*
//* MESSAGES FROM THE REXX EXEC WILL BE WRITTEN
//* EITHER TO JOBLOG
//*    SYSTSPRT DD SYSOUT=A
//* OR TO USER SPECIFIED DATA SET
//*    SYSTSPRT DD DSN=XX.YY
//*
//*
//TRACE   EXEC PGM=IKJEFT01,DYNAMNBR=30,REGION=4096K
//SYSEXEC DD   DSN=SYS1.SBLSCLI0,DISP=SHR
//SYSTSPRT DD   SYSOUT=A
//SYSTSIN  DD   *
