Yes. You need to have FETCh and then followed by CALL for the Fetched module.
Usaully we cod as follows:
Code: | DCL module_name EXTERNAL ENTRY(PTR) OPTIONS(FETCHABLE);
CALL module_name(PTR); |
Or
Code: | DCL module_name EXTERNAL ENTRY(PTR);
FETCH module_name;
CALL module_name(PTR); |

Actually, you do not need the FETCH if you have RELEASE. The compiler will spot one of these and realise that the called module will not be linked into the main load module and will generate the necessary code. However, it is not wrong and I always do FETCH/CALL/RELEASE in my own programs. _________________ Utility and Program control cards are NOT, repeat NOT, JCL. |

You should start new thread for a new topic.
COPY is a directive to the compiler to copy in some source code into your source code before it compiles it.
CALLing a program happens when your program is already executing and it CALLs another program to do some function.
This is probably something that you could have found out by looking in the index of the manual for COPY and CALL. _________________ Utility and Program control cards are NOT, repeat NOT, JCL. |
