I am new to DB and DBpro, however, I’ve been programming many languages for 15 years. I have a Jet which flies around in 3D, which looks good. I am wondering how do I know which way the jet is facing so I can do the proper rotate to make the jet roll into a turn? Will I have keep track within my program? (hope not)

Has any one else run into a problem multiplying a number by -1 within DBpro? For example:

A = 7
A = A * -1
A now = -1
If I then multiply A by -1 again it stays -1.

Thanks, I love what I see so far in DBpro

Maybe there's a problem with compiler optimizations?

a=7
a=a * -1
print a
a=a * -1
wait key

Does display -1 in both caces, but :

a=7
a=a *-1
print a
a=a *-1
print a
wait key

doesn't - seems to be a parsing error

Yes, I really am THAT good...
