Tracing the AOPPRINT procedure

Turning trace on: To trace the AOPPRINT procedure, specify the AOPTRACEON=1 environment variable in the STDENV DD statement in the procedure. You can specify AOPTRACEON in-stream. Start in the first column, and do not code any blanks in the string or at the end of the line:

//STDENV DD *
AOPTRACEON=1

Turning trace off: To stop tracing the AOPPRINT procedure, comment out the AOPTRACEON=1 environment variable in the STDENV DD statement in the procedure:

//STDENV DD *
*AOPTRACEON=1

If the STDENV DD statement points to a data set, comment out the STDENV DD statement in the procedure.
