From **PC Magazine, Vol. 6 No. 1, p. 121**:
|
||||
The RatBas Translator was a preprocessing utility created in 1982 by William F. Sharpe and Brent D. Weaver that
|
||||
could translate a structured dialect of BASIC into code compatible with IBM BASIC. It was described extensively
|
||||
in a [PC Magazine (October 1982)](#article-from-pc-magazine-october-1982) article.
|
||||
|
||||
The only copy of RatBas we've been able to locate is version 2.13 from a
|
||||
shareware CD-ROM titled "[PC-SIG Library Eighth Edition From PC-SIG (April 1990)](http://cd.textfiles.com/pcsig08/)"
|
||||
on [DISK0003](http://cd.textfiles.com/pcsig08/001_100/DISK0003/).
|
||||
|
||||
We have archived it as [RatBas 2.13](#directory-listing-of-ratbas-213). It has been loaded in drive B: in
|
||||

Another alternative, however, is one that makes it possible to obtain the advantages of interpretive execution of BASIC

and also write programs with good structure and at least some modularity. The needed ingredient is a preprocessor.

A preprocessor translates programs written in a modified language to equivalent programs written in the target language.

The target language is MicroSoft BASIC, as implemented on the IBM Personal Computer. The modified language is called
