2.3.3.2.1.7 Database Unit User Defined Symbols
USERDEF
This parameter allows the user to define a symbol and a
value that will be substituted for the symbol by JCLGEN.
This can be used in a user modification to PROTOLIB to
provide user defined symbolic elements. Several USERDEF
symbols may be defined. The only restriction is that
the symbol on each USERDEF statement must be different
from those on all others and different from all symbols
currently used by JCLGEN. Also, the value must end
before column 73 of the record. For example,
USERDEF DIGITS 0123456789
would define a symbol DIGITS. Anywhere this symbol
appeared in a PROTOLIB member, JCLGEN would substitute
the string 0123456789 in its place.
Note that PROTOLIB is shared by all databases in a
complex, so any user symbols which appear in a member of
PROTOLIB must be defined in prefix.MICS.PARMS(JCLDEF)
for all of the database units which may reference that
PROTOLIB member.
