HP 50g Compare Strings? - toml_12953 - 09-01-2014 12:03 PM

How do you compare the contents of a variable to a string in algebraic notation on an HP 50g? I've tried both the following ('a' contains either "Y" or "N")

Code:

IF ' 'a' == "Y" ' THEN

IF 'a == "Y" ' THEN

Of course neither one works. So how do you do it?

TIA

Suggestion: Don't use an algebraic. Just use IF a "Y" SAME THEN.

That works, thanks! You should be canonized, but I can't find my cannon at the moment. ;^)

No need; I'm already a canon regular. Big Grin

An absolutely perfect setup like that does not come along every day Wink

You win!

BTW, I figured out how to do what I originally wanted to do. To test for a string in algebraic notation, enclose the test in reverse quotes (the character just before the lowercase a in the CHAR screen.)

This works:

Code:

IF `a=="N"` THEN
