Hi,
There are several flavours of "PIC BASIC" from different vendors and manufacturers. This forum, as you know, is really only targeting the compilers from MicroEngineering Labs. So when you see a reference to "PIC Basic" on the net or in a book, make sure you understand which manufacturers compiler they are really talking about.

If you're talking about comparing the features of the original PIC BASIC Compiler from MELABS to the PRO version of the same compiler I don't see the purpose since the old version is discontinued. Besides, if you think PBP is complicated you wouldn't want to use PBC.

If you want to compare the three different version of PBP3 then you can do so here. As far as I know all commands are available in all versions, however the experimenter and silver edition is limited in the number of supported devices. The silver edition, for example, does not support 18F series and therefor you can't use LONG variables.
