Choosing the DYNAM or NODYNAM compiler option

When you run under:

• TSO or IMS: You can use either the DYNAM or NODYNAM compiler option.

  Note that IMS and Db2® share a common alias name, DSNHLI, for the language interface module. You must concatenate your libraries as follows:

  • If you use IMS with the DYNAM option, concatenate the IMS library first.
  • If you run your application only under Db2, concatenate the Db2 library first.
• CICS® or the Db2 call attach facility (CAF): You must use the NODYNAM compiler option.

  Because stored procedures use CAF, you must also compile COBOL stored procedures with the NODYNAM option.
