If you're looking for a quick way to create system compliant programs, you'll undoubtedly consider Swift!BASIC a wise investment.
In and of itself, Swift!BASIC is a remarkable product for the HP 95LX. It works as advertised and is a good value for the money.
As with any new language product, using the first edition is somewhat risky. Undiscovered bugs may lurk somewhere in the program. These are the kind of bugs that show themselves only to early users of the language. However, if enough people learn use the language, it will grow and mature through several revisions.
Hopefully, you'll find yourself growing along with it.
