Ok, I already have a tool to convert old "noextend" basic+ to the newer "extend" format. It is 'b1filter.cc' in the src directory of git clone http://github.com/khandy21yo/btran.git it handles the end-of-line stuff as well as the '&' for print. There are some things it doesn't handle, like

Re: [Simh] Simh Digest, Vol 168, Issue 38

We ran into this on a real VAX when we added a 20GB SCSI disk, as I recall. Either VAX/VMS or the hardware (I think it was VAX/VMS) only looks at the low-order 24 bits of the disk size. So, our 20GB disk was viewed as a 3+GB drive on the VAX. Alpha/VMS has no problem handling larger drives.

Re: [Simh] VAX Tape Emulation?

As far as I am aware, there is no limit, up to the amount of disk space available. Backup Save Sets are just RMS sequential files with fixed record lengths (on disk, usually 32768 bytes, on tape, I think the default is 4096, except 2048 for Interchange format). Larry Baker US Geological

Rsts basic+ has two modes. Extend and noextend, Noextend is the original mode, where 'line continues with a linseed and ends with a return. The & character works as a shortcut for print. Statements were separated with a colon : Extend mode was changed things around. It was a later addition.

If it was applicable to the situation, then VMSTPC would work great. It’s already installed on my Alpha, and I’m pretty sure there is a VAX binary for it in the VAX directory on there. I also have it installed on my RSX-11M+. It’s definitely a great tool. Just not for this. :-) Zane > On
