DEFINE PRAGMAS: STACK POSITION AND SIZE (2)

Although ugBASIC is a stackless language, it can still interact with the processor's stack. Not all processors allow you to change the size and position of the stack, and sometimes there are limitations due to hardware features (e.g., consoles). As with other instructions, ugBASIC's isomorphism still allows the instruction to be used on processors that have a programmable stack.

How to compile and run the example

The instructions here refer to compiling the example from the command line. For Microsoft Windows users we suggest using UGBASIC-IDE, which allows you to download and compile each single example with just one click.



Are instructions for your specific home computer / console missing? First of all, check if your computer is supported by clicking here. If so, since ugBASIC is a language which does not provide abstractions, it is possible that this example will not work on your target. If you think this is an issue, please click here.
