# Simple Mods for ZXAS & ZXDB

The [BUG-BYTE](http://localhost/company/bug-byte-software/) [ZXAS](http://localhost/product/zxas/) assembler and [ZXDB](http://localhost/product/zxdb/) disassembler/debugger comprise a fairly powerful machine level programming package. In this article I will describe a few simple modifications to the BASIC portion of each program which will make them all little more convenient to use. I will also describe memory usage of the two packages and show you where to assemble your code.
