Developing Compaq COBOL Programs
1.2 Developing Programs on Tru64 UNIX
Table 1–3 lists and describes some of the software tools you can use when
developing and testing a program.
Table 1–3 Main Tools for Program Development and Testing
Task or Activity Tool and Description
Manage source files Use RCS or sccs to manage source files. For more information,
see the Tru64 UNIX documentation on programming support
tools or the appropriate reference page.
Create and modify
source files Use a text editor, such as vi , emacs , or another editor. For
more information, see your operating system documentation.
Analyze source code Use searching commands such as grep and diff . For
more information, see the Tru64 UNIX documentation on
programming support tools or the appropriate reference page.
Build program (compile
and link) You can use the cobol command to create small programs,
perhaps using shell scripts, or use the make command to build
your application in an automated fashion using a makefile.
For more information on
make , see the make(1) reference page
and the Tru64 UNIX documentation on programming support
tools.
Debug and test program Use the Ladebug Debugger to debug your program or run it for
general testing. For more information on Ladebug Debugger,
see the Ladebug Debugger Manual.
Install program Use setld and related commands such as tar . For
more information, see the Tru64 UNIX documentation on
programming support tools.
In addition, you might use the following shell commands at various times during
program development:
• To view information about an object file or an object library, use the following
commands:
The file command shows the type of a file (such as which programming
language, whether it is an object library, ASCII file, and so forth).
The nm command (perhaps with the -a or -o flag) shows symbol table
information, including the identification field of each object file.
The odump command shows the contents of a file and other information.
The size command shows the size of the code and data sections.
For more information on these commands, see the appropriate reference page
or the DIGITAL UNIX Programmer’s Guide.
• Use the ar command to create an archive object library ( -r flag), maintain
the modules in the library, list the modules in the library ( -t ), and perform
other functions. Use -ts to add a table of contents to the object library for
linking purposes. For more information, see ar(1) or the DIGITAL UNIX
Programmer’s Guide.
• To create shared libraries on Tru64 UNIX systems, use ld , not the ar
command. For more information, refer to Section 1.2.3.4 and the DIGITAL
UNIX Programmer’s Guide.
