BlueEarth, LLC sells microcontrollers based on an updated version of BASIC-52. We also sell two software programs to deal with the line-number problem.

1. The BASIKIT program is like a terminal program, but it is specifically designed to talk to a BASIC microcontroller. It supports a full-screen edit mode. It also includes a handful of utilities, including ones to remove line numbers from a BASIC program source file, add line numbers back in, renumber them, check for invalid variable names, etc. I have found these programs to be indispensible for developing all but the most simple BASIC programs.

2. The BEC-51 BASIC compiler, which was developed by the original BXC-51 compiler author. This program creates an assembly language file that accomplishes the identical functions of the interpreted BASIC program, without the overhead (and many of the limitations) of the interpreter. It also allows you to write programs without line numbers.
