Just thought I'd mention... There have been observations that viewing PDFed manuals online is a drudge, making one want to keep hardcopies of TSM manuals to flip through to quickly get to information. Having had only hardcopy manuals my first 20 years in data processing, I understand.
I've been a Macintosh user since about 1986 and recently got a G5 for my office workstation. In Mac OS X (whose standard document model is PDF) is an application called Preview, for viewing PDF and graphics file. Its speed is incredible, making online PDF use a joy. I used Acrobat Reader before this - which was the speed of a tortoise...enough to discourage anyone from viewing PDFs on-screen. But Preview is like lightning: as you type the phrase you want to find, Preview is already finding hits for you. By the time I've finished typing the phrase, it has found them all. If you have any say in your workstation choice, this is the way to go. I can now search a huge manual in seconds. I never bother with hardcopy manuals any more, saving lots of storage space and much personal time. Richard Sims
