Address Finder is a super simple tool to find the address a program on disk loads into memory.

DECHEXBINOCT is a simple program that shows how a number is represented in decimal, octal, hexadecimal and binary systems.

This handy little programmers tool by M.J. Kozakiewicz lets you compare two areas of memory and print out the differences to screen or printer. You set the size of the memory block and only the addresses that hold different values are output. Instructions are included on the disk. Remember to load with just a ,8 and not ,8,1.

Program Analyzer is a neat tool to find out all kinds of information about a program.

SYSRES is an operating system which works in conjunction with the BASIC operating system in your Commodore-64 to give you, the programmer, advanced program and file manipulation ability. The syntax has been carefully selected to be as similar as possible to many other such systems, while adding a host of additional features.  

SYSRES is designed to be addictive to programmers but NOT addictive to programs. This means that no commands are added or changed in the way in which they behave within a program. Software developed under SYSRES is fully compatible with a non-SYSRES environment.  By using an extremely powerful syntax structure, SYSRES adds over 1100 new functions to BASIC, while only using 33 new command words (plus 1 1 dos-support commands). Even with all of this power, SYSRES Is very simple to use, because most commands accept syntax with which you may already be familiar; the more powerful features are optional.  

SYSRES hides away under BASIC, so it USES NO RAM which would normally be available to BASIC programs (except 256 bytes from $COOO to $CFFF for BASIC interface)(Ref: pp. 2-3). One reason SYSRES is not in a cartridge is that a cartridge takes 8K away from your BASIC RAM.

Total Software Development System (TSDS) by Piratebusters Software is a collection of tools used for developing software.  Here is a quick blurb from a review by Chris Zamara that I found in TPUG News Volume 1, Number 2:

At first glance, TSDS appears to be just a colletion of standard utilities: an editor enhancement utility a la BASIC aid, an assembler, a sprite editor, a character editor, and a sound effects generator - the kind of thing to make a jaded programmer yawn. After using the package for a short while, however, it becomes obvious that the programs in TSDS are the product of a programmer who has created high quality tools for his own use, and honed those tools to a keen edge.

The Ultimate Tools 2.0 is two programs that can be used for aiding in the typing in of programs from the Compute! and RUN magazines.  Not really sure if anyone still does that, but if you do, then you will want to use one of these programs to help you catch typing mistakes and speed up the whole process.

Universal Program Lister by Jim Butterfield and published by Compute! in December 1982 is a tool for all Commodore computers that can list a BASIC program to screen or printer.  Here is a quote about the program from Mr. Butterfield himself:

"There are lots of Lister type programs around. This one isn't much different, except that it is very complete. It runs very slowly; have a cup of coffee
while it's running."
