Each record of the input parameter data set must contain the name of an initialization/termination program or an access method driver, starting in column 1. The name can have up to eight characters, including the characters A-Z, 0-9, @, #, and $. The first character cannot be 0-9.

To distinguish access method drivers from initialization/termination programs, include the TYPE keyword in the input record anywhere between columns 9 and 72. An access method driver must be followed by the keyword TYPE(A); initialization/termination programs can be followed by the keyword TYPE(I) or by no keyword.

MVSSERV invokes all initialization/termination programs it finds in the input parameter data set, but invokes only the first access method driver it finds, ignoring any other TYPE(A) programs.
