To get X>=Y? you must type XEQ "X>=Y?" which should resolve to X>=Y?. The problem is that it doesn't resolve. It stays as XEQ "X>=Y?" I tried X<=Y? and it works correctly. The actual keystrokes are:
XEQ
Alpha key
X
USR
Shift TAN (to get >)
USR
=Y?
Alpha key
Any ideas on what I am doing wrong? Thanks.

Re: Problem with entering X>=Y?
You are simply trying to use a non-existent conditional.
On the 41 you have to negate the test and use X<Y?
See https://literature.hpcalc.org/community ... qrg-en.pdf page 25.

Re: Problem with entering X>=Y?
X>=0?
X>=Y?
Code: Select all
X>=0? // missing test
INST. // instruction to execute if true
Code: Select all
X<0? // reverse test
FS? 30 // always false (catalog in progress flag)
INST. // instruction to execute if true
Code: Select all
X>=Y? // missing test
INST. // instruction to execute if true
Code: Select all
X<Y? // reverse test
FS? 30 // always false (catalog in progress flag)
INST. // instruction to execute if true

Re: Problem with entering X>=Y?
That must be correct but the test is listed in one of the Hp41cx manuals.

Re: Problem with entering X>=Y?
It’s a typo in the manual, it should be X#Y? which is mentioned on the line below and by similarity with X#0? above.
DM42: 00425 - DM41X: β00066 - WP43: 00042
Re: Problem with entering X>=Y?
That's a typo: you can check that the same comparisons are used with regards of 0 and Y; on the line above the fourth instruction is X≠0? while on the second line, at the same position, you find that (wrong) X>=Y?. Finally, on the bottom row are mentioned x=y? and X≠Y?; this last one is not mentioned before, but it is what you really have available.
X≠Y? missing from the second line, is what should be printed there at position 4.
