Re: Is Learning 2 Programming languages at once possible?
@Camlorn, please read exactly what others post about programming languages before you go on rants like you did in post 9. You did not realize what Danny was saying. He did not say that everyone should use PB. He just said he's comfortable with it. Again, I ask you nicely to re-read Danny's posts.
Edit:
PB is not C in any way, shape or form. It does not have the syntax that C has; it does not use any C libraries whatsoever; and it does not generate C code and then use another compiler to accomplish its goal. It, in fact, uses pure assembly. Every single library is written in assembly and converted to binary code using the Flat Assembler (fasm.exe on Windows, fasm on Linux, and Yasm on OS X). When you compile something, it translates your code to assembly and then assembles and links the code.
As an example, I'll demonstrate this in practice:
In PB, asking the user for input is as simple as doing:
PrintN ("Enter a message.")
Inp
ut()
When compiling PB code, the compiler takes this code and translates it into the following:

; (c) 2014 Fantaisie Software

; The header must remain intact for Re-Assembly

That is what happends during compilation: Write PB code, check the sntax, covert the code to ASM, check the ASM code with FASM, assemble it, and link it to produce an executable program.
