Well, I finally have begun the task of weeding out my formula file. I printed the formulas, which resulted in close to 600 pages of output and a sorely depleted toner cartridge. One thing that I noticed is that the 2000 formula limit must be somewhat arbitrary. Many of my older formulas are only a line or two while some of my current formulas are close to the 2500 character limit. In theory, the formula file could contain 2000 formulas each with 2500 characters, or the formula file could contain 2000 formulas each with only 1 line of code. Either way you would receive a message that the formula file is full, while the smaller file may be less than 5% the size of the larger file. That being said, I tend to think that the formula file limit of 2000 formulas must be somewhat arbitrary.
A huge undertaking will be involved in weeding the formula file, but no doubt that I will learn many things from the experience.
