HDELETE

use HDELETE to migration file deletion is good a choice.

sample:

//STEP0010 EXEC PGM=IKJEFT01
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
HDELETE filename                  PURGE
HDELETE filename                  PURGE

if it's for all files:

//STEP0010 EXEC PGM=IKJEFT01
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
HDELETE 'HLQ.**' PURGE

take care of '    if use like 'FILENAME1  ', will return 18, shoule just use FILENAME1 or 'FILENAME1'.
