Activate the MFX dictionary feature by specifying a SYMNAMES DD statement which defines your dictionary statement data sets.
The dictionary statements can be contained in a physical sequential data set, a member of a PDS, or DD *. Each data set must consist of fixed-length, 80-byte records.
You may specify multiple dictionaries by concatenating data sets with the SYMNAMES DD.
The following sample application illustrates the use of the SYMNAMES DD * .
