completely destroys it!

Thanks. It's fixed now.

TAN(90) because error 14 is “TAN=Inf”.
it should be:
TAN(90) because error #4 is “TAN=Inf”.

Thanks! Fixed.

[Dwight Sturrock]

Thanks Joe, very nice.
I have the original book, and it made the 71 comprehensible.

In page 121, line 170 should be POKE DTH$(A), C$ @ POKE DTH$(A1),A$

And when entering the REVLEX example, for the last entry line there is a missing '-' in the display ... (it display 006: -------)

Should line 90 be A$=A$&C$ @ A=A+37 @ N=N*2+32 @ Q=3 @ SFLAG 5 ?

Regards and thanks for this wonderful manual

Thanks. I poked the missing dollar signs into that line, and uploaded it.

Quote:And when entering the REVLEX example, for the last entry line there is a missing '-' in the display ... (it display 006: -------)

The checksum was misplaced. It's now in the correct column.

I don't think so. The listing of MAKELEX in my book, as well as the actual MAKELEX program on the CHHU01 swap disk and on the ATCHCO swap disk, all have +31 in line 90, not +32. I haven't tried running it with +32 instead. Have you?

To Joe: Thanks for the chance to re-read it again (my copy is in storage). Brought back lots of fond memories. I'm still humbled at the credit.

To All: If you've not had the chance to meet Joe in person, he's very much as you'd suspect when you read this book. A tremendous fount of humor, knowledge, empathy, enthusiasm and all-around goodness. Yes, I'm biased, and proud to be.

Many thanks for this. I almost read it cover to cover this weekend.

Code:

30 X=IP(MIN(MAX(X,1)16))

This is from the CMDSTK program. It's obviously missing a comma before the 16.

Me too. Great read.
Too bad it's all history now.

I find the HP-35S heaps more useful today; it beats even the greatest HP-41, IMHO!

On the nice website of Joe : http://holyjoe.org/HP71/lexlist.htm I encountered a nasty bug : the lex SHOWPORT lead to a memory lost on my HP71B (rev 1BBBB-HPIL 1AAAA)

The entry was ok for the checksum, the first use display some info then 'memory lost'

Sorry to hear that, but I just verified that the hex listing there is correct, so that's not what caused your crash. I strongly suspect that your copy of the MAKELEX program (in your HP-71) contained an error. Did you save MAKELEX on cards or print a listing from your '71? If so, please compare it character by character with the listing in the book.

Minor nits:

Page 28: "REAL-WORLD EXAMPLES..."
Last word should be "USAGE"

Page 80: The table at the top could be realigned.

Page 85: "HOH TO EXPAND..." should be "HOW TO EXPAND..."

After fixing those errors and re-saving the file using Nitro PDF, the file bloated from 1.63MB to a ridiculous 3.84MB for no apparent reason. The original bookmarked version was less than 1MB! Does anybody have a tool that can LOSSLESSLY* minimize the size of a PDF file? Thanks in advance for recommendations. Note: I tried an online PDF minimizer; it nuked several tables.

Edit: *Losslessly = by removing only invisible, unnecessary junk, like perhaps editing history(?), redundant formatting, that sort of thing.

[Dave Frederickson]

I ran the "Reduce File Size" tool in Acrobat which reduced it to 828 KiB.

Edit: File removed as it was obsolete.

THANKS!!! The online version has been replaced with yours. I guess I gotta buy Acrobat.

Have you tried the Export to PDF function of your word processor? Both Word and OpenOffice offer this option.

[kakima]

More nits (does this seem like an infinite loop?):

Page 4: Chapter 7 "clock" probably should be "Clock" (capitalized) for consistency

Page 38: INT(X) the greater-than-or-equal-to should be less-than-or-equal-to

That's how I made the original non-bookmarked version, but then Bill added the chapter bookmarks. Rebuilding it from Word would lose those bookmarks.

Incredible: Nitro PDF Pro 6 can't paste the "≤" character from Word (!), so these two fixes are #2 on my To Do list. #1 is: Get Adobe Acrobat.

I'm surprised you've never taken the LaTeX route, Joe.

I checked this MAKELEX twice before using it.
I used this MAKELEX to enter REVLEX and it was working ... perhaps it is a bug linked to the HP71 rom rev (I have a 1BBBB + HPIL 1A)

[Dave Frederickson]

SHOWPORT was written for 1BBBB firmware as it's already in the 2CDCC version. I've used this LEX file with no problem. You have HP-IL so have you tried loading the file from disc or the PIL-Box?

You should consider splitting this topic off onto it's own thread as it has nothing to do with Joe's book.
