CALL and ENTER Statement Processing: Detailed

Explanation

2. If program S contains a common program named A, and also contains (directly or

indirectly) program P, then if P calls A, the compiler chooses the common program

In Example 11-6, the compiler issues a warning if a file-mnemonic appears. If

common program A contains program P (directly or indirectly), the compiler leaves

P’s reference to A unresolved, and Item 4 applies.

3. If neither Item 1 or Item 2 applies, and a previously seen separately compiled

program has the name A, the compiler chooses that program.

4. If Item 1, Item 2, and Item 3 do not apply, the compiler conducts a search for

program A.

If file-mnemonic appears, the compiler tries to find a separately compiled

program unit in the file associated with the file-mnemonic. If the compiler

cannot find such a program unit, it reports an error and delivers no object code for

program S to the target file.

If no file-mnemonic appears, the COBOL85 compiler consults the search lists.

If the compiler finds no separately compiled program A in the object files of the

search lists, the compiler expects a separately compiled program A to appear

somewhere within the source text, and also expects all of program A’s parameters

to have EXTENDED-STORAGE access mode (the default).

If the compiler does find a program unit for A in the search lists, it resolves the

reference with the first such program unit in the list. If the compiler discovers a

separately compiled program A later in the source text, it replaces its previous

resolution with the new one. If the new program A and the original program A have

different numbers of parameters, or if their parameters have different access

modes, the compiler reports an error and delivers no object code for program A to

the target file.

5. When the compiler reaches the end of the source text, it issues a warning if it was

unable to resolve any program references. You must supply the missing programs

(using BIND or the linker) before you execute the loadfile.
