Report and Label Utility -- RL.EXE
Create and modify report (.frm) and label (.lbl) files

RL
System Architecture
The RL system is written in Clipper. If you installed the default
configuration of the development environment, the source code is
located in the \CLIPPER5\SOURCE\RL directory on the disk where Clipper
5.0 is installed. RL.EXE is installed in \CLIPPER5\BIN and this
directory is included in the PATH statement in your AUTOEXEC.BAT. You
should, therefore, be able to access RL from any drive and/or
directory.
The source files needed that make up the RL system are:
. Rlfront.prg
. Rllack.prg
. Rldialg.prg
The system is provided as source code so you can modify it to suit your
specific needs. You may want to make enhancements specific to your
development environment or simply add the RL system to your application
thereby giving your users the power to create their own reports and
labels.
To facilitate modification, the RL system is broken up into two primary
subsystems: front and back. The RL front subsystem (found in
Rlfront.prg) is the user interface of the entire RL system. The back
subsystem (found in Rlback.prg) contains all of the routines for
reading and writing (.frm) and (.lbl) files. The system is organized
in this way so that you can create your own user interface and easily
access the lower-level routines to read and write the form files.
If you decide to tailor this system by making changes to the source
code, a make file, RL.RMK, is located in the same directory as the RL
source code. Provided that your changes do not involve additional
source modules or changes in the existing file dependencies, issuing
the following command at the DOS prompt:
C>RMAKE RL
will compile and link the system to create a new RL.EXE file. Refer to
the Program Maintenance--RMAKE.EXE chapter in the Programming and
Utilities book for more information.
