Hi all,

Does anyone have a copy of this program from the HP19c/29C applications book. The one I have from my Museum flash drive is missing steps 48 and 49.

cheers

Tony

From my copy (same source) the lines are visible:

48: 5
49: -

Maybe that copy of the file is damaged, or maybe I don't misunderstand your request?

Thanks,

45  ST+1

46  RCL1

47  RTN

50 RTN (at top of next column)

51 *LBL 0

cheers

My bad, without the exact page, I was looking at the prior program in the Queen Board Chapter.

I have 2 original copies of this manual, and they are not only different from what you've described, they are also different from each other.

The first manual, which appears to be the same as the version in the MoHPC scan (same covers, inside title page, etc.), includes line 48:

44 1
45 ST+1
46 RCL1
47 RTN
48 *LBL 7
Test for good position
===========
50 RTN (at top of next column)
51 *LBL 0

but no line 49, although the comment for that line is visible (as it is in the MoHPC copy).

The 2nd copy I have is marked on the back cover "5955-2111 Rev. B 9/77"

This copy gets it right:

44 1
45 ST+1
46 RCL1
47 RTN
48 *LBL 7
49 RCL2 Test for good position
================
50 RTN (at top of next column)
51 *LBL 0

Quite an interesting find, thanks for that Tony.

Hi Bob,

Thanks.

Sorry I meant only line 49 was missing and replaced with your code and now it works :-)

All good now, I had a few problems with others but after some fiddling they work too.

cheers

from my 'errata' archives: data & full source unreferenced with doc

HP-19C/29C Programming Problems
The Queen Board game on pp. 52-54 of the applications book will work if you add step 49 "RCL 2", and change step 79 "GT09" to"GT05".
