so I updated the MODPARAMS.DAT, rebooted and ran NETCONFIG.COM, but I'm getting errors when attempting to reach out over the ethernet. I know the physical network connection is OK because tcpip is working fine. Cohort in crime points out that you do need to do the autogen dance to get those modparams changes noticed, and that the lavc stuff may nail up the interface before decnet gets there, so scssystemid and nodeid matching may be important here.

De Well, I never thought this would fix a VMS issue, but rebooting it solved the problem. Sorry for wasting your bandwidth ;) Thanks for the help!!! Mark.

Slightly OT - How to concatenate multi line strings in DEC COBOL

Anyone? :) OK, well, my suggestion for these kinds of problems is 'DECUS archive'. If I ever get my semantic web browser up and running it will make this kind of issue trivial ;) In the meantime I did a manual search of packages in the archive containing both 'C' and 'COB' files. This was the list I got: ./vax89a1/cvlug/escdemo/escdemo-c.c ./vmslt01b/vu/cdwrite15_vms.c ./vmslt01b/vu/chkpw.c ./vmslt01b/vu/enable-ide.c ./vmslt01b/vu/fast_io_copy.c ./vmslt01b/vu/grant_revoke_id.c ./vmslt01b/vu/ide-info.c ./vmslt01b/vu/iishack2000-printerexploit.c ./vmslt01b/vu/rwmbx.c ./vmslt01b/vu/tcpfilter.c ./vax91b/france_1991/vaxf91a/vms/copy_folder.c ./vax91b/france_1991/vaxf91a/vms/get3.c ./vax91b/france_1991/vaxf91a/vms/latsym$setup.c ./vax91b/france_1991/vaxf91a/vms/mall.c ./vax91b/france_1991/vaxf91a/vms/show_cursor.c ./vax90b1/france/vaxf90a/vms/decw$creterm.c ./vax90b1/france/vaxf90a/vms/photo.c ./vax90b1/france/vaxf90a/vms/shar.c These are C files contained in packages that also contain files with extension .COB They are rooted here: http://www.decuslib.com/decus/ http://www.decuslib.com/decus/vax91b/france_1991/vaxf91a/vms/ In there are a number of COBOL files. I single out one here: find_file_with_selection.cob this calls a number of external routines for example: * On retrouve l'adresse de l'Item Liste CALL "LIB$ANALYZE_SDESC" USING BY DESCRIPTOR ITMLST BY REFERENCE DUMMY1 ITMLST_ADDRESS. CALL "LIB$MOVC3" USING DUMMY1 BY VALUE ITMLST_PTR BY REFERENCE ITMLST_MASK. * Taille du BUFFER... CALL "LIB$GET_VM" USING TAILLE_BUFFER BY REFERENCE BUFFER_ADDRESS GIVING RETCODE. IF RETCODE IS FAILURE THEN GO TO FIN. * Attributes BLOCK : NBR_ITEMS * 8 + 4 MULTIPLY 8 BY NBR_ITEMS GIVING TAILLE_ATRBLK. ADD 4 TO TAILLE_ATRBLK. CALL "LIB$GET_VM" USING TAILLE_ATRBLK BY REFERENCE ATRBLK_ADDRESS GIVING RETCODE. IF RETCODE IS FAILURE THEN GO TO FIN. Hopefully with a few examples of calling external routines within the archive you should be able to figure out what you need to do.

Slightly OT - How to concatenate multi line strings in DEC COBOL

by Paul_Koning＠Dell.com

Maybe because the VMS people made the assumption that any language can call any other, so no specific documentation is needed? That was one of the goals of VAX, and it should have carried to Alpha. So assuming that the data type mapping is clear, nothing else should need to be said. paul On Sep 12, 2012, at 3:22 PM, Sampsa Laine wrote: Well I always wanted to play with COBOL lol. It's just infuriating how there's no decent docs on how to call a damn C function anywhere. I mean there is for DEC UNIX COBOL, but not VMS.
