RCHKA-Record Code Check

This general macro provides a variable value (1-254) for the CHK field of the data record header. This is done by using the global field @RCHKA, which is modified each time RCHKA is issued. The GLMOD and FILKW macros are issued in the macro expansion to allow modification of @RCHKA.
