PowerBASIC provides a number of ways in which you can use assembly-language. You can write the whole program using the Inline Assembler. You can write entire Subs, Functions, Methods, and Properties in assembly-language, or, you can write individual lines of code in assembler, surrounded by BASIC statements. This ability to intermix BASIC and assembly-language, line by line, makes PowerBASIC's Inline Assembler a very powerful tool when optimal performance is an essential issue.
To write good assembler code, you must be aware of certain items:
| · | The types of variables supported by PowerBASIC |
| · | How those variables are stored in memory |
| · | How to use variable names in your Inline Assembler routines |
| · | Which registers to save (and restore) |
| · | How to pass arguments (to and from Inline Assembler routines) |
| · | The need to pop everything you push |
| · | The differences between near and far calls |
| · | The rules to follow when writing assembly-language routines |
