[Simh] hp alternatives

[Dan Gahlinger]

yeah I kinda doubt that.
they don't work even close to the same

I work code using indexed files and could even index off of arbitrary text in a comment field.
I know of no other solution that can do this.
its because vms was doing all the heavily lifting behind the scenes.

I could do a read based on comment field which wasnt indexed or a key, and doing cyclical reads it would recall records in sequence based on that arbitrary text.
without that field being a key or being indexed.

for testing on simh I dedicated the largest drive I could to a single indexed file.

I had ideas on how to get it to use nfs or so and use much larger data files but never got around to seeing what's possible.

I think I liked vms solution because its elegant, no fuss or muss to use

I have been able to replace RMS indexed files with BerkelyDB without many issues so that is one alternative.  Just have to replace I/O statements with functions that do the appropriate calls.

is there a way to port vax basic?
please dont say visual basic, it's awful.

heck even vax Pascal is vastly different from free Pascal.

dcl? nothing remotely like it really, bash?

how about indexed files?
rdbms is a poor man's alternative.

vax vms is truly unique.
and will always be my favorite.

Since GP is exiting the VMS arena, and dropping the hobbyist licenses, I was wondering about alternatives for running old VMS code.

There are plenty of C, FORTRAN, etc compilers on Linux/etc, but if there were comparable VMS libraries (open source) for things like RMS, SMG, LBR, etc, then many programs culd be run on other platforms.

I know there are commercial products like these, BUT The licensing doesn't help hobbyist who want to share code.

Are there any of these available? I've done a few functions to convert VMS calls to Linux calls before, but only for a few functions.

I just thought it would be another way to simulate some of VMS st another level than simh/vax/vms.
