|HP35s Program Memory Quirk|
Message #1 Posted by Thomas Chrapkiewicz on 10 May 2009, 2:30 p.m.
I've just been documenting/scrolling through my HP35s's program memory. I have the machine set for 100 data memories, and have about 150ish lines of code in it under about 15 different labels.
When scrolling through 'line count' program memory
[via the <-MEM 2] menu, downward, I will find a LBL ; that the list seems to be stuck at. Repeated attempts to scroll down past this label has no result - the LBL ; continues to be displayed.
Keying <-SHOW displays a checksum of 1C5A for this strange label.
Scrolling up through the program list can proceed with no ill effects.
Scrolling down again will again hit this strange LBL ; [with the same resultant checksum].
Has anyone else experienced this?
ps: BTW, this is a relatively early HP35s [CNA72103302].
pps:Also, (FWIW) my first line in PRGM memory is an unlabelled GTO X001 - this gives me a quick 'GTO . . R/S' which displays owner information.
