- Agreed, but :-

- [ LMI FORTH has files & blocks, floating point ... etc. ]

- they've [LMI users] had access to these capabilities, if they

- And I'm sure they are happy with them, but consider what happens if
- they decide, for one reason or another, that they don't want to use
- LMI FORTH anymore, but prefer to use a different vendor's system.
- What are they to do with all the code they've developed using LMI
- specific extensions? Unless the "extensions" are either standard or
- defacto standards then there may be significant effort involved in
- changing the code, so much so you may have to stick with the system
- you have even though you know you can get better/cheaper elsewhere
- (I've suffered just this situation with large amounts of code written
- using VAX FORTRAN + extensions). This is good for vendors since it
- keeps users locked into their system, but it is definitely not a good
- deal for users.
