PostProcessing.bat

[puck64]

Hi Sub,

Just a quick question before I start to write an ooRexx script to replace PostProcessing.bat.

When PostProcessing.bat is called is it called as "PostProcessing.bat" or " PostProcessing " (no extension) ?  

I understand Rexx better than Windows CMD (bat)

[sub]

It's called PostProcessing.bat on Windows, or PostProcessing.sh in Linux.

Thanks Sub,

So the Windows NextPvr.exe uses "postprocessing.bat"

I sort of worked that out .... I wrote a rexx program (PostProcessing.rex) and renamed the bat file to .batold and had no joy.
I then renamed ....batold to bat and called the rexx program from postprocessing.bat.
All is good till I try and use the channel number, its always 2
The filepath and filename are ok

Have I got the bat file right
here is my post processing.bat

"@ECHO off
setlocal EnableDelayedExpansion
ECHO Start Conversion1 of %~f1 ON %2  >> Conversion_Log.txt
call rexx Processing.rex %1% %2%
"

[sub]

Honestly, I know nothing about rexx. I'd imagine you'd have use a normal PostProcessing.bat, and call your rex program, somewhat like your example above.

I'm pretty sure command line arguments are like %1 and %2, not %2% etc used in your batch file. I'm no batch file expert though, so don't know if these trailing percent characters have some specific meaning. I wondered if that is why you always get "2" though

Thanks again Sub,

I used to be a Mainframe PL/1 Programmer, Rexx is very much the same. So I use Rexx as a scripting language.

The little bit of DOS I know is what I can find on the Internet, and that is sparce.

I will play with the Parms and see what happens

As far as I can remember (and I'm definitely rusty on command line programming)...

%1% and %2% would represent variables defined with the label 1 or 2. Your batch file doesn't define the variables before using %1% or %2%

Assuming you want to pass arguments 1 & 2 that are given to Postprocessing.bat to your rexx programme, I think you should be using %~1 and %~2

Not 100% sure but you may need to include those in quotes i.e. "%~1" and "~%2" (as I said a bit rusty on this   )

call rexx Processing.rex "~%1" "~ %2"

Hi Bobins,

Well that put me on the right track

All I had to do once I found that both variables came across as 1 was separate them

NOTE:- Say in Rexx is the same as Echo in DOS/Windows Command

My PostUpdate.bat looks like this ....
@ECHO off
rem setlocal EnableDelayedExpansion
rexx Processing.rex %~1 %~2

AND my Rexx Program  (Processing.rex) looks like this ....

/* rexx */
trace off

parse arg passed

say 'passed = '||passed

full_path_fn = substr(passed,1,LASTPOS(" ",passed) - 1)

say 'full_path_fn = '||full_path_fn

j  = LASTPOS(".",full_path_fn)
fn = substr(full_path_fn,1,j - 1)

chan = substr(passed,LASTPOS(" ",passed) + 1)

say 'fn  = '||fn
say 'chan = '||chan
pause

j      = 0
Weather = 0

Weather = POS("Weather",fn)

If you want to pass through the variables as is from the batch file to your application all you need is %*

Using call is for batch files, embedded spaces on the parameters will be fine and don't forget your paths.

Code:

@echo off
/pathto/rexx.exe  /pathto/Processing.rex %*

If you want it to run in the background or if is a GUI exe read up on the start command.

Thanks Martin,

Another great Idea to try.

I don't usually use "rexx Processing.rex", its usually "Processing" as rexx is in my path

The environment for the server may be different than then your user environment and it certainly never hurts to fully qualify it.
