If you make this registry change to run doperl.bat instead of perl.exe for .pl files, then it will also affect perl scripts run from the command line. All command line scripts would then pause for user input before proceeding. I don't think this would be appropriate for the default ActiveState installation. ;-)

Have you noticed the new wPerl.exe in the 6xx series? Found out what it does yet? On NT you can type:

ftype plwfile=wperl.exe "%1" %*
assoc .plw=plwfile

and rename your files from .pl to .plw.

This is a pet peeve of mine...

Unless you pause the program with

print "Hit Return to continue ..."; <STDIN>;

the DOS window will vanish immediately after execution.
And if you have a syntax error in your program
(who does not?) even the above line will be of no help to you.

I think the default (after installation) way of running a perl
script on Win 32 should be to wrap it in a batch file like so:

doperl.bat
----------
c:\perl\bin\perl.exe  "%1" %*
@pause
----------

If the above file is in place in c:\perl\bin
and the registry is configured to invoke:

c:\perl\bin\doperl.bat  "%1"  %*

rather than

c:\perl\bin\perl.exe  "%1"  %*

then the program will always pause allowing you
to see what happened even if there is a syntax error.

Perhaps have a different suffix (and a separate registry
entry) for invoking perl.exe directly???

And how about a registry entry for editing perl programs
in notepad.exe??????   That would help new people understand
that perl programs are pure text files.

Jon

P.S.  I am not a DOS expert so I'm not exactly
sure what that "%1"  %* is.  Something about
command line parameters.
