Introduction to SCUP

For example, executing the command

SCOBOLX/IN TESTFILE/ MANUF;

causes SCREEN COBOL to compile SYMBOLS the program in TESTFILE, and to

generate directory entry MANUFDIR, object code file MANUFCOD, and symbol table

MANUFSYM.

SCUP automatically processes all three associated object files. A diagram of

SCREEN COBOL object files is shown in Figure 1-1.

The SCREEN COBOL object files can contain several different programs, several

versions of a program, and optionally, several versions of a symbol table. The

compiler does not overwrite the previous contents of the files when it adds a program

and the associated symbol table to the object files. Instead, the compiler appends the

code to the code file, adds the symbol table to the symbol table file, and inserts the

program name and version number in the directory file.

The version of the program and its symbol table is 1 if previous versions do not exist in

the specified SCREEN COBOL object file. For example, TEST-PROG(2) refers to the

second version of the program called TEST-PROG and the second version of the

symbol table for that file, that is, the second time the program called TEST-PROG is

added to the specified object file either through compilation or through the SCUP copy

function.

The highest version number always represents the last version added to the object file.
