running many files through the same command

Hi everyone,

not sure if the subject of this thread is a good way to describe what I =
want to do, but here it is. Basically I wish to convert several (many) =
files from WordPerfect format to T602 format. For this, I have a small =
utility "pre602.exe" which functions in this way:

PRE602.EXE [parameters] inputfile outputfile

In my case, let's say I wish to convert a file called "text.wp", I would =
do:
pre602 /d:5 text.wp text.602


Question 1
Imagine I have twenty files I want to convert, and I don't want to do =
each one individually. Is there any way to do this using a batch file? =
If I put all those files in one folder, is there any way how to generate =
a list of those files, and then run this list through the pre602.exe =
command automatically?


Question 2
I want to define a custom action for .wp files which would do the =
conversion to .602. I was able to do something like this:

pre602.exe /d:5 %1 new.602
However, I am not able to figure out a way to refer to the part of the =
filename before the file extension, and thus I had to make the output =
file something fixed, which I subsequently have to rename. I know "%1" =
refers to the file that the action is taken on. If the file is, say, =
"xxx.wp", is there any way to refer just to "xxx"?

Thanks for your input.

Ivan
