Message from Charles Daney about The REXX Cookbook

I just scanned an advance copy of a new book on OS/2 REXX, called The REXX 
Cookbook, by Merrill Callaway. He's publishing it himself, and I have also 
uploaded a file (RXCKBK.TXT) to library 6, (CompuServe-Forum OS2DF1) which 
contains a press release and overview of the book. 
I found this a very interesting book that OS/2 users of REXX might want to 
consider. Although it starts off assuming little background in 
programming, it covers a lot of the REXX language. Though it is not 
without some small errors, Callaway has put in an impressive amount of 
work on this book. It's one of the most detailed computer books I've ever 
seen, and not just trivial detail either, but good solid information. And 
some of the examples are among the best I've seen anywhere. 
Though I didn't really look at it as a tool for actually learning 
programming, it does have introductory chapters. But it also has entire 
chapters devoted to topics like debugging, REXX as a macro language, 
interprocess communication (including a lot about SQL and DB2/2), VX-REXX, 
and the use of PostScript from REXX. I have no financial or other 
connection with this book - just thought that OS/2 users interested in 
REXX should look into this, since it is very different from the usual dry, 
boring computer manual and has a high content of real meat.
