I have path like
C:\Sound\Classical\...
C:\Sound\Jazz\...
I want to know if Classical is in the path so I use an expression
IsEqual(Classical,FilePath(),8) – this yields 0 all of the time
IsEqual(FilePath(),Classical,8) – this yields a 1 if Classical is in the path.
The tooltip say IsEqual compares 2 values.
It look likes in case of a substring compare this should be interpreted as find the second value in the first value.

I'm familiar with Marko's Magnum Opus, great job.
Nowhere is specified that in case of a substring search the sequence of the parameters is of importance.

It does now :)
Regardless of the specified mode, the first value is always compared with the second value.
I put a lot of effort into not taking anything for granted when writing that page up. It wasn't easy. I guess that's one that slipped through the net.
Hopefully, you're finding the page otherwise useful.

Hi Marko
IsEqual(A,B,param)
When testing for equality sequence doesn't matter
When testing for > or < than of course it does.
In case of a search for a substring there is no logic.
Find A in B or find B in A are both perfectly valid.
I'm inclined to say as we do compare A with B most of the time; find A in B is slightly more 'logical' than find B in A.
However it is clearly documented now.
One suggestion:
Note that when using compare modes seven and eight, the subject must be given first, and the term to compare for given second
