PowerBASIC
The history of PowerBASIC compilers goes back over 25 years. That's when Bob Zale, PowerBASIC's founder, created BASIC/Z, the first interactive compiler for CP/M and MDOS. It was extended to MS-DOS, and in 1987 Borland published it as the now legendary Turbo BASIC. The compiler became officially known as PowerBASIC in 1990 when Bob Zale founded PowerBASIC Inc.
MaintainJ
MaintainJ have been working on Java since 1997 being actively involved in the design, development and maintenance of large Java applications. Maintaining Java applications that have grown over time can be difficult and time consuming especially if you were not the original developer and have to analyze the code first to find out what it is meant to do. MaintainJ provides a better way to understand complex Java applications and was built for and tested on large real-world applications.
