Binder Language to Export Tax Rate Data

Figure 1. Binder Language Source to Export Tax Rate Data
          STRPGMEXP PGMLVL(*CURRENT) EXPORT SYMBOL('taxrate')
           ENDPGMEXP
Note:
  1. The Start Program Export (STRPGMEXP) command identifies the beginning of a list of exports from the service program T1520SP1.
  2. The Export Symbol (EXPORT) command identifies the symbol name taxrate to be exported from the service program T1520SP1.
  3. The symbol name taxrate, identified between the STRPGMEXP PGMLVL(*CURRENT) and ENDPGMEXP pair, defines the public interface to the service program T1520SP2. Only those procedures and data items exported from the module objects making up the ILE C service program can be exported from this service program.
  4. The symbol name taxrate is enclosed in apostrophes to maintain its lowercase format. Without apostrophes it is converted to uppercase characters. (The binder would search for TAXRATE, which it would not find.)
  5. The symbol name taxrate is also used to create a signature. The signature validates the public interface to the service program T1520SP2 at activation. This ensures that the ILE C service program T1520SP1 and the ILE C program T1520PG1 can use service program T1520SP2 without being re-created.
