Compiling DataFlex Programs
by Curtis Krauskopf
Summary
Multiple files can be compiled on one
command line by using the FOR
command parameter. The FOR
command can be used on both the command line and inside
of a batch file.
Compile-time error alerts can be suppressed
but recorded in .ERR files
by appending a -v1fskn
parameter to the dfcomp
command line. dfcomp is
somewhat braindead when it comes to compile options.
The following command line will not work:
| Incorrect:
dfcomp -v1fskn menu.src |
This will try to compile the file -v1fskn
and completely ignore the MENU.SRC
parameter. The correct way to format the above dfcomp
command is:
| Correct:
dfcomp menu.src -v1fskn |
By making use of the echo,
if, ERRORLEVEL
and shift Windows batch
commands, a fairly intelligent batch file can be created
that allows a programmer to compile multiple groups
of source files using wildcards on one command line.
The batch file is even friendly enough
to detect when no parameters were provided, and to automatically
handle the housekeeping of deleting .ERR
files from previous batch compilations.
I
hope that you enjoyed this article and learned something
interesting about DataFlex and Windows batch files.
Let me know if you liked it (or not). Your feedback
will help guide me when writing future articles.
