Index tag expression

[JimEkleberry]

Anyone know how to obtain an index tag's expression programatically?

Say I execute: INDEX ON fname + lname TAG fullname

I can use the TAG() function to obtain the index name of fullname but I need the fname + lname portion.

Check help for the sys(14)- index expression which should give you what you want. I use this in an array and let the user see which index (and expression) they want to use.

I just checked and it turns out that there is a KEY() function that does the same thing. Surprisingly, it isn't listed in any of the See Also tags or as a function.

I'll take a look at the SYS(14) function as well. Thanks for the help!
