Compiling the Program

CA IDMS Precompiler

The CA IDMS precompiler modifies the program that you submit. CA IDMS comments out SQL statements and substitutes calls to the DBMS. The entire source program is now in compilable form.

Here is an example of an SQL statement that has been commented out by the precompiler, and the code that the precompiler has substituted:

 011200*    EXEC SQL

 011300*         FETCH CURS1 BULK :EMPDATA
 011400*           START :INDEX-CNTR ROWS :NUM-ROWS
 011500*    END-EXEC.
                  MOVE 4 TO SQLCLNO
                  MOVE 16 TO SQLCMD
                  MOVE 1 TO SQLARG
                  MOVE 4 TO SQLSID
                  MOVE 278 TO SQLTBL
                  MOVE 6 TO SQLMRO
                  MOVE INDEX-CNTR TO SQLSRO
                  MOVE NUM-ROWS TO SQLNRO
                  CALL 'IDMSSQL' USING
                                SQLRPB
                                SQLCA
                                SQLCA
                                SQLCIB
                                SQLPIB
                                SQLCA
                                EMPDATA
                                SQLCA
                                SQLCA
                                SQLCA
                                SQLCA
                  .

Language Compiler

To compile the program, you submit the source program, as successfully modified by the precompiler, to the language compiler. Output from the compiler consists of an object program and a source listing.

Link Editing

The linkage editor edits the object program into a specified load library. Output from the linkage editor consists of a load module and a link map.

Note: For JCL and more information about compiling and link editing a program see Sample JCL.
