AESTing SCAN images on Itanium

[Malcolm Davies]

Hi,

We are testing a new Itanium development box, and we have some tools that rely on Scan images when building Decforms (replacing token placeholder code with language specific variants).

We have AEST'd the SCN exe's on the Itanium system using AEST defaults, but are now getting errors - without associated SCN message libraries we are a bit stuck trying to figure this out and no longer have a Vax with Scan on to look for the message, any suggestions or advice would be welcome at this point (Does anyone have a Vax with Scan message libraries who could translate the error code below?).

Some details:
$ scan_form_input_file = "scr:PATCH_REQUEST_FORM.IFDL"
$ scan_form_tags_file = "obj:PATCH_REQUEST_FORM.tags"
$ scan_form_panels_file = "scr:PATCH_REQUEST_FORM.panels"
$ create_panels_file = "Y"
create_form_tags_file_scn.*
$ run/nodeb utl_rel:[exec]create_form_tags_file_scn
%SCN-F-NOMSG, Message number 0132809C
$get_out_err:


Thanks,
Malcolm

Malcolm,

Licensing issues aside, if you need a VAX system to check things out on (and you have your old backup files), you can use SIMH or Charon-VAX.

SIMH is available at http://simh.trailing-edge.com
Charon-VAX is available at http://www.charon-vax.com

Both effectively provide the ability to run an emulation of VAX hardware on an Intel IA32 Windows system.

Malcom,

there is a CHARON-VAX/Freeware for OpenVMS I64 download, which would enable you to emulate a VAX running on OpenVMS I64 (with 1 VUPS only, but it works). So if you still have the BACKUPs of your VAX system disk, this may also be way to go.

Scan is available natively on OpenVMS Alpha

http://www.emulatorsinternational.com/en/vaxscan.htm

You could contact them to see if they have or plan to have it on OpenVMS I64

Volker already answered using his tool.
I would like to add the manual version.

SGDEV6::MM:000000 >SET MESSAGE SYS$MESSAGE:SCN$MSG.EXE
(B) SGDEV6::MM:000000 >WRITE SYS$OUTPUT F$MESSAGE(%X0132809C)
%SCN-F-FILPRVCLS, Close failed - file not open

On our system (IA64, VMS 8.2-1) the SCN$MSG file is installed by default.

Maybe it is time to replace your scan code.
It was a good idea at the time, but it's getting too tricky now.

The task you describe sounds like relatively suiteable for a perl script.
Its regular expressions make token recognition relatively easily and you'd be working with a language the many more people know and/or are willing to learn.

fwiw,
Hein.

Thanks for the great responses. I have followed up a few of them. Firstly we have now defined the correct logical for SCN$MSG and so see the error message correctly.

Secondly, I contacted emulators international who said as only 2 people use the Alpha version, no way they would do IA64 unless we were willing to pay for it. Following this, the suggestion to rewrite in Perl sounds promising. We do have the original code, so this should be straight forward. Until then I will be checking the file open/close sections of the code to see if I can track down the error, maybe even creat debug version of image using AEST.

thanks,
Malcolm

Following advice from the forum, we tracked down an incorrect logical pointing to the sys$library:SCNRTL.EXE image, problem now resolved.
