Positional parameters depend on their position in the "string of parameters" you send to the receiver. You can't change their order, and if you want to omit a positional parameter, you have to supply a placeholder (usually - a comma).
Keywords are more convenient when you send a large amount of parameters, as they are more clear to the sender. You specify each parameter in the format of keyword=value.

Examples:
- Keywords: "DCB=(RECFM=FB,LRECL=100,BLKSIZE=27900)"
- Positional: "PARM=(&PROG,,&DATE)"

Again - it depends how the receiver expects to receive the parameters. Read your relevant documentation carefully - usually it specifies the parameter type.
