## How do I test for in-equality, "A\$ <> B\$" & "A <> B"...???

### How do I test for in-equality, "A\$ <> B\$" & "A <> B"...???

Greetings,

How do I test for in-equality, "A\$ <> B\$" & "A <> B"...???

There must be a work-around but i don't know it.
Any help is much appreciated.

Good morning Robert

Please give an example what you want to test for inequality, and for what purpose. Maybe, then we can explore possible options.

Best regards

OK, i gather this is not as simple as i thought.
How i was wanting to use it is:

IF x\$ <> z\$ THEN...
&
IF X <> Z THEN...

Is this what you meant Andries?

Hi Robert

Do you want to test if both items are unequal?
Code: Select all
`x\$="abc"y\$="ac"x=2y=3IF x\$<>y\$ AND x<>y THEN    PRINT "both pairs not equal"ELSE    PRINT "one pair is equal"ENDIFEND`

Thanks Daniel,

Nowhere in the manual does it state that "<>" is valid, nor does it show any examples anywhere.

The closest it comes to is in page 18 of the manual where it says:

Valid expressions contain one of the five relational operators =, <, >, <= and >= and variables or constants.

It should also say:
Use "<" and ">" together to test for inequality, example: IF abc\$ <> xyz\$ THEN...

You can see why i questioned it...

Thanks again for spelling it out Daniel.

Enjoy!

Hi

Point taken. I will update the manual to reflect the fact that there are six relational operators.

Apologies Robert! I did not fully understand your question the first time. I assumed that you new how to use the <> operator in Control Basic.

Thanks for pointing out the omission in the manual.
