how can I convert the fellow C file to pascal

The Fellow is a head file on dialogic,I want to control
D/41es with delphi.

I will send it again. Maybe it got lost.
I use the DOS editor Brief for most changes.
The search & replace expressions are very powerful.
First convert the comments to Pascal syntax.
The #define constants go with a set of replacement macros.
The records are done by hand.
Exchanging parameter type and parameter name is also done with a set of replacement macros.
The rest of the changes are again done by hand.

I have already converted a megabyte or two so your conversion was an easy one.
Better send me the file directly to
I will give it a try.

robert_marquardt,thanks for your help,I have send the file
to you .
Keep up with what's happening at Experts Exchange!

Sign up to receive Decoded, a new monthly digest with product updates, feature release info, continuing education opportunities, and more.

and i have cut it out already and converted as far as possible :-)
I forgot to mention: i added some "// (rom)" comments where conversion was not possible.

thanks robert_marquardt,I wait for your mail.

   I am amazing for your quicking.I wanner do you do it by tools.for I have used the tool named h2pas,but it do not work well
