Migrating BASIC programs from VAX 810ft to Alpha DS20
i tried to migrate these BASIC programs to the DS20 running in VMS 7.2. but when i run these programs in the DS20, i encounter irreplicable errors in the output.
do i need a conversion tool to make it run properly? do i need a new OLB (object library) and then re-compile it?

Re: Migrating BASIC programs from VAX 810ft to Alpha DS20
Basically engineering has tried to give us "source compatibility" between VMS on VAX, VMS on Alpha, and VMS on Itanium.
But all three architectures have their own "features".
You should compile your Basic sources, and link your programs on the Alpha, and then of course test them.
Migrating from a VAX environment to an Alpha environment isn't that complicated, but can be time consuming.
Unfortunately, I cannot connect to the HP VMS site (at http://h71000.www7.hp.com/) right now. But there you can find documentation on how to migrate your apps from VMS on VAX to VMS on Alpha.

Re: Migrating BASIC programs from VAX 810ft to Alpha DS20
You have two ways to migrate programs from VAX to Alpha.
1) If you have all sources, recompile them on the Alpha (this is the best way).
2) Use VEST which translates VAX exe programs to Alpha exe. (to be used when you have not all sources)

Re: Migrating BASIC programs from VAX 810ft to Alpha DS20
The HP VMS site seems to be up again (although terribly slow).
Here's the link to the doc:

Re: Migrating BASIC programs from VAX 810ft to Alpha DS20
You say you get errors when you RUN the programs.
Can we presume that they compile OK?
I have moved BASIC code from VAX to Alpha and
also to Itanium with minimum effort.
Recompile, relink and run.
Exactly what errors are you getting?
