DCL TO SCRIPTS

Suporte Operação — Tue, 16 Nov 2004 12:41:04 GMT

Hi all!

I would like to know if there is any software that does the conversion of OPENVMS DCL scripts to HPUX (Unix) .sh scripts.

Someone knows about it??

Thanks

Cido

I don't know of any and I think that automatic conversion would not be possible due to the very different designs of VMS and unix.
The utilities, file system etc are different as well as the command syntax.

I think you would have do examine each DCL procedure in turn to determine what it did and then implement the equivent on hpux - if it makes sense in that environment.

Perhaps a product from Channel Islands might help you get to where you are going by another route.

Specifically, Channel Islands has/had a product called DCP, which takes DCL to FORTRAN. You could then take the FORTRAN source and compile on HPUX to get working code, perhaps.

http://www.kgb.com/dcl/199109.txt speaks of the product and company. I have no idea if Channel Islands is still in business or not.

Your mileage will vary a lot on this approach, I would guess.

Hello Cido,

as Ian pointed out, an automated translation
is most probably not available.

If you just want to save some typing, write a script in your favorite language (DCL, Unix shells and Perl come to mind e.g.) to do simple string substituion (copy -> cp, rename -> mv,
write sys$output -> echo). Note that this will just accomplish that, you still need to read and understand each script to do the right thing on Unix.

Another possiblity might be to actually run the DCL scripts on Unix. You might want to check out http://www.accelr8.com/migprod.html
for this.

And the last and absolutely best solution is to migrate your Unix shell scripts to DCL on VMS, since it is the better environment anyhow ;-)

Cheers, Martin

Hello Cido

I don't know if exists some free software to migrate DCL commands to UNIX but this link provides a commercial software (I don't tested this).

Godd luck.
