Hey All. I have a pretty complex script that contains a
bunch of for...do loops. Is there a way to split the
lines to make it more readable? The example below is just
one line of this monster. It basically takes all the
matching files in a directory and compiles them. If the
executable is generated it increments a counter and if a
flag is set writes to a log otherwise it writes a fail
message to the log.

for %%F in (%LocalFormsSrcDir%\bas*.pll) do start /w
C:\orant\bin\ifcmp60 module_type=LIBRARY
module_access=FILE batch=YES window_state=MINIMIZE userid=%
ProdDBConnectString% module=%LocalFormsSrcDir%\%%~nxF
output_file=%LocalBinDir%\%%~nF && if exist %LocalBinDir%\%
%~nF.plx (set /A NumPllCompiled=NumPllCompiled + 1 & if %
FullLoggingFlag% == Yes echo Compiled %%F ... >> %
LogFile%.log) else (echo %%F Failed!! >> %LogFile%.log)
 
You can put a caret ^ character at the end of the line to continue it.

However, be sure there are no space characters or any other whitespace
following the ^ character.

Line 1^
Line 1 continued^
Line 1 continued on line 3
Line 2
Line 3

Assemble long commands in a var, use additional parenthes, after an
open parenthes continue on a new line, change the logic to use goto's
and call :Internalsub instead of stuffing all in a single line.
If you already use parenthes there is no need to use & to put the
following command on the same line.

That is a little tto complex for what I'm trying to do
(just trying to make the silly thing more readable).
Thanks for the advice though...
 
That seems to do it. I miss the white space but for now
it at least makes the script a bit more readable. Thanks
for the advice...

Really? Try this combination of Paul's and mine tips:

for %%F in (%LocalFormsSrcDir%\bas*.pll) do (
start /w C:\orant\bin\ifcmp60 ^
module_type=LIBRARY ^
module_access=FILE ^
batch=YES ^
window_state=MINIMIZE ^
userid=%ProdDBConnectString% ^
module=%LocalFormsSrcDir%\%%~nxF ^
output_file=%LocalBinDir%\%%~nF && if exist %LocalBinDir%\%%~nF.plx (
set /A NumPllCompiled=NumPllCompiled + 1
if %FullLoggingFlag% == Yes echo Compiled %%F ... >> %LogFile%.log
) else (
echo %%F Failed!! >> %LogFile%.log)
)
