I am going to answer the questions provided for reviews:
Q1: Does the program improve upon other versions of similar programs? How?
A1: No. It is just a copy of MirageOS. Even the beta of v4 looks like a watered-down MirageOS.
Q2: Are there features that enhance the program? Lack of features?
A2: Well, the calc off feature is only functional on the TI-83 Plus family. Attempt to do so on a TI-84 Plus family calculator will crash it. It is too slow, but I don't blame Pat Stone for it. BasicBuilder is supposed to do that. The password lock is a waste of time. Delete the lists involving "BES", and you are back to normal.
Q3: How easy is the program to operate? User friendly?
A3: User friendly, yes. Easy to operate, no. It takes too long to move. What else? Say you have a program called AAAPRGM. If you have AAAAPRGM before AAAPRGM, it won't scroll to AAAPRGM. You can't run AAAPRGM that way.
Q4: What would you like to see changed, added or removed?
A4: It needs to be completely rewritten, which I believe Patrick is already doing. However, news has been idle since 7/17/2006. I think BES has been abandoned.
Q5: As far as TI calculators goes, is this program original?
A5: No. It's a bad MirageOS all over again.
Q6: Who would you recommend the program to?
A6: No one. I hope BES4 surpasses MirageOS, and increases compatibility with TI-84 Plus (Silver Edition)s.
BES is better than any BASIC shell though. There has not been a single BASIC shell that has even come close to the abilities of BES.
