- Re: The Programmer's Guide to CP/M
-
- This message is of interest to owners (and prospective owners) of
- Andy Johnson-Laird's superb THE PROGRAMMER'S CP/M HANDBOOK
- (Osborne/McGraw-Hill), and is based on recent correspondence from
- the author.
-
- In the original edition, about two pages of listing were not
- printed. The missing listing is lines 04628 thru 04919 (see page
- 261-262). Anyone who wants the missing lines can get them from
- the author's office: Johnson-Laird, Inc., 6441 SW Canyon Court,
- Portland OR 97221. Send a SASE with a note on what you want.
- (Johnson-Laird said the book went into its 2nd printing in
- January 1984, and the missing material should be in that 2nd
- version. But he is out of the country on a project and tells me
- he has not seen the 2nd version.)
-
- Other errors in the book:
-
- . page 64, figure 4-3, location 0153, correct to read:
- JM CTPX (instead of MB CTPX)
-
- . On page 149, 7 lines from the bottom, there is a reference
- to CCP+6. That reference should be CCP+0. The letter
- from the author said that there may be other such
- erroneous references, for CCP+6 is a CP/M-86 convention
- and thus the source of the error, but he has not found
- other such errors.
-
- . page 258, line 03828, change this line to read:
- STA MOB$Character
-
- . page 282, after line 09270, insert:
- LXI H,Disk$Control$5
- (Note: after inserting that line the byte references will
- be offset by 3 bytes, if you type it all in and assemble
- it.)
-
- Finally, Johnson-Laird wants to know about any other bugs, typos,
- errors and what have you that anyone may spot. You may send such
- information DIRECT to me and I'll relay to Johnson-Laird.
-
- If you have not yet seen the book, look at it. If you buy it,
- you'll probably not lend it out -- it's too valuable to do
- without for anyone who has any notion about playing around with
- 8080 assembler and CP/M in general.
