Positional & keyword parameters are very important at JOB,activity & DD level.
We have these parameters for each level i.e JOB, ACTIVITY & DD .

Positional  Parameter: 

  • These positional parameters are mandatory which must be coded after operands with minimum one task.
  • Mainly we use two parameters at the JOB level i.e
  • Accounting Information : - This parameter must be coded immediate after the operand and it should contain1 to 20 alphanumeric characters.
