Name field

The entries allowed in the name field of a model statement, before generation, are:

Space
An ordinary symbol
A sequence symbol
A variable symbol
Any combination of variable symbols, or system variable symbols such as &SYSNDX, and other character strings concatenated together

The generated result must be spaces (if valid) or a character string that represents a valid assembler or machine instruction name field. Double-byte data is not valid in an assembler or machine instruction name field and must not be generated.

Variable symbols must not be used to generate comment statement indicators (* or .*).

Notes:

You cannot reference an ordinary symbol defined in the name field of a model statement until the macro definition containing the model statement has been called, and the model statement has been generated.
Restrictions on the name entry of assembler language instructions are further specified where each individual assembler language instruction is described in this manual.
