State the difference between positional parameter and keyword paramete

1.	State the difference between positional parameter and keyword parameter in JCL.
Answer» Positional Parameters: Positional parameters are those that FOLLOW a fixed position in terms of the order in a statement JCL. Their order in the JCL statement is ALWAYS fixed therefore they should be specified in the specified order. Changing the position of the positional parameters will RESULT in an error in the JCL. Examples: ACCT (ACCOUNTING Information), PGM (Programmer Name), etc. Keyword Parameters: There is no need for a fixed position for these parameters. It doesn't matter in what order you code the keyword parameters; you won't get any errors. Examples: TIME, REGION, MSGLEVEL, CLASS, etc.
