DD name list format
When you call the precompiler, you can specify a list of alternative DD names for the data sets that the precompiler uses. You must specify this list in a particular format.
The DD name list must begin on a 2-byte boundary. The first 2 bytes contain a binary count of the number of bytes in the list (excluding the count field). Each entry in the list is an 8-byte field, left-justified, and padded with blanks if needed.
The following table gives the following sequence of entries:
