The Tokenized Parameter List

To create a tokenized parameter list, CMS truncates or pads each argument in the input data to 8 bytes. The first token must be the name of the program you call. In addition, CMS treats each parenthesis as an argument and it appends an 8-byte fence (delimiter) of X'FF' to mark the end of the tokenized parameter list.

SCAN stores a pointer to the tokenized parameter list in general register 1.
