Table 1 lists Enterprise COBOL compiler options relevant to COBOL IMS applications.
| Compiler option | Comments |
|---|---|
| RENT | The RENT compiler option causes Enterprise COBOL to
produce reentrant code and allows you to place the COBOL modules in the LPA
(Link Pack Area) or ELPA (Extended Link Pack Area) and thus shared among dependent
regions under IMS. Also, the modules cannot be overwritten, since the LPA/ELPA
have a storage protect key. RENT allows you to run your IMS programs in either preload or nonpreload mode, without compiling with different options. |
