Developing Programs With System Tools

Compaq provides tools to develop source code and to generate and manage the object

files. Object code is generated with the SCREEN COBOL compiler. The resulting

object files are managed with the SCREEN COBOL Utility Program (SCUP).

Generating Object Files With the Compiler

To produce the SCREEN COBOL object files, you execute the compiler run command

SCOBOLX. The compiler generates the object code according to the compiler

commands specified in the run command and in the source code.

The SCREEN COBOL compiler has three associated processes (SCOBOLX,

SCOBOLX2, and SYMSERV). These processes generate the object code, which is

written to two or three files depending on selected compile options. The SCOBOLX

and SCOBOLX2 processes produce two object files—a directory file and a code file.

The optional third process (SYMSERV) produces a symbol table for the program.

Note. The SYMSERV process is not one of the Pathway/iTS object files. Therefore,

SYMSERV must reside on the same volume as SCOBOLX and SCOBOLX2 when used to

compile a SCREEN COBOL program.
