Save Your Fingers, Save Your Eyes

Remember that all the source programs which appear in the Apple Assembly Line are available on disk, ready to assembly with the S-C Assembler II Version 4.0.  Every three months I collect it all on a Quarterly Disk, and you can get it for only $15.  QD#1 covers AAL issues 1-3 (October thru December 1980), and QD#2 covers AAL issues 4-6 (January thru March 1981).  QD#3 will be out at the end of May, covering issues 7-9.  Some AAL subscribers have chosen to set up a standing order for the Quarterly Disks, so they get them as soon as they are ready.

Not only does it save you a lot of typing time.  You also are saved the hours you might spend looking for the inadvertant changes you made while you typed!


Another Utility from RAK-WARE

Bob Kovacs is sure keeping busy!  Last month he announced the Cross Reference Utility which works with your S-C ASSEMBLER II source programs.  This month he has a Global Search & Replace Utility ready (see his ad on page 4).  It is a nice companion to his disassembler, because it gives you a fast way to change all the labels made up by the disassembler into meaningful names.

If You Need Disks...

For a limited time, I am able to offer you a good price on Verbatim DataLife disks.  These are bulk packaged, 20 to a pack, with no labels and with white sleeves.  They are the same ones I use myself.  I will send you a package of 20 for only $50.
