I curious, can you remember which ones?

I think it was a SDS Basic or a variant.

OK, thanks. I've not used that. The problem I had was that I learned Fortran before coming across BASIC, so converting Fortran programs was often a problem when features where missing.

I looked again and the basic I remember was on the HP 9845B that I used for a while.

Thanks for that. I've just checked the link and will do so again in more detail.
