    For a quick BASIC routine check this environment is one of the best I have tried - more convenient than most DOSBox options. Sticks to the adage that BASIC implies Briskly Achieve Solutions Impossible in C. It's a permanent install on my computer now.

    Full disclosure: I am the main author, so obviously I think PC-BASIC is great! I'm developing and maintaining this in my spare time, but I'm able to respond to questions fairly quickly. While I think it is now very usable and many people will be able to use it without any issues, PC-BASIC is actively developed and not yet entirely stable. PC-BASIC is intended to mimic an old and not very user-friendly piece of software, so necessarily it will have a bit of a learning curve. Do check out the documentation on this site; the same files are also in the download package. But if you can't get it to do what you need, don't hesitate to ask on the forum. If you run into bugs, or would like to request a feature, please leave a message on the forum and check back occasionally. That way I can get back to you to ask you for more information, for example to be able to reproduce the bug or better understand what you're trying to get done. You'll often hear back within a few days, if not quicker. Note that SourceForge offers no way for me to open a dialogue like that on a review, so please do not use the reviews section for bug reports. It makes it very difficult for me to get the information I need from you to solve the bug. Rob

    Well, I tried to run TERM.BAS (The terminal emulator written in BASIC) on MacOSX, it fails when trying to open COM1: but the PCBASIC program, doesn't allow you to map a port, if for some reason you desired to use the serial ports." (TERM) - Terminal Emulator Device Unavailable in 140 Ok  list 140 140 CLS:PRINT ID$:CLOSE:OPEN"COM1:,,,,CS,DS" AS 1:CLOSE

    Would be great if it could be installed to a standard directory and started from anywhere.

    Really simple and effective GW-Basic emulator... if someone was looking for such a thing, this is a simple and nice solution, I think easier than using Dosbox or another full featured emulator.
