I've encountered problems with embedded programming on every language 
that I've used so far.

   You're doing embedded code now, not working on a PC.  Bascom supports 
pretty decent amounts of math, but b^3 is not something that I've used 
in an embedded processor.  Things that that for trancendentals or 
whatever tend to be interpolated from tables, not calculated in the 
limited abilities of little embedded processors.  I do think that Bascom 
has a weird requirement that _no_ implied variables can be used (for 
instance B*3+1 can't be done because there is an implied temporary 
variable needed between the two operations) but that is simple to get 
around, and perhaps enlightening for newcomers to the embedded world to 
not assume anything.

   Did you go there with an attitude on or "playing nice"?  I will 
guarantee you that if you go to any on-line group with a chip on your 
shoulder you'll get the boot.  Don't EVEN ask a newbie question on the 
guru Java lists!

   The manual is as good as Microchip's C18, and what manual do you get 
for GCC?  I've found Mark to be very helpful with bugs.

   I think Bascom is a very good compiler for the money, and a very good 
educational tool for teaching embedded to those that are new to the concept.


IMO, YMMV,
