How to get .hex from this code??

[ScaleRobotics]

I have seen some codes, where guys had something like:

#include < blablabla.h >

Does i need some .h file to be included?

Right you are. The code looks like it was written for a Basic Stamp Pic Chip. For this, just add the include at the top of your program, then it will compile without errors.

DEFINE OSC 20       'define crystal speed. This is 20 mhz
include "bs1defs.bas"    'lets you use definitions same as Basic Stamp 1
