Using the PARM parameter for loader options

Use the PARM parameter of the EXEC statement to specify loader options in your JCL for loader processing. For example, if you want your application to run even if abnormal conditions are detected, and you want a mapping of the executable program, specify the following: 
//GO EXEC  PGM=LOADER,PARM='MAP,LET'
