Compiling From Within

Michael P. Dean

Ever want to compile all of your programs in one easy step? You could
use the BUILD program, but, wouldn't you rather do it from within
dBASE. PrgComp will do just that! Then, if you want just one .DBO
file for distribution, you can use the DBLINK program to link all off
your .DBO files into one .DBO file (see Programming with dBASE IV for
instructions on the dBLINK.EXE program). Programming with dBASE IV
comes with the Developer's Edition of dBASE IV. The documentation for
dBLINK is also available for download from our BBS (DBLINK.DOC)

PrgComp.PRG will also
ù Compile Screen formats (FMT), Report Forms (FRM), Labels
(LBL), Queries (QBE) or Program files (PRG).

Create a database file of all files in the directory of your
choice with the DOS file size and date.

ù Create a .DAT file that contains a list of all files that were
compiled with all error Messages that were encountered during the
compile process. All the Object files will be in the directory that
the source code files existed but the .DAT file and the database file
mentioned above will be in the directory that the PrgComp program
exists.

ù Show the file that is being compiled and a line count of the
lines that are being compiled, except for reports and labels, where it
shows the name of the template of the report/label.

And, here is all that you have to do. Create a database file called
PrgComp with on field called PrgName with a size of 31 and index set
to Y. This file must be in the directory with PrgComp.PRG (which does
not have to be in every directory that you have .PRG files, it only
has to be in one directory). When you start the program, if the
directory that has the PrgComp program in it is in your dBASE path, or
if PrgComp is in the directory that has the programs that you wish to
compile just type

DO PrgComp WITH "",""

and PrgComp will compile all the files of that type in the current
directory. If however, you are in the directory that contains the
PrgComp files and you wish to compile programs in another directory,
just type in

DO PrgComp WITH ":",""

For example

DO PrgComp with "C:\Mydir","FMT"

will compile all screen forms in the Mydir directory of drive C.
Notice that there is no ending backslash.

The file type can be FMT, FRM, LBL, QBE or PRG
