Do you have any unusual codepage set, or SET COLLATE?

ISTR there's a keystroke command that dumps all the SETs to the Command Window (IIRC), but I can't remember what it is. Anyone?

Could you post the results of that, or of LIST STATUS?

  • at() is case-sensitive. You can use atc() instead, if you want to find text in any case.

  • You may want to issue the command SET STEP ON right before you use the at() command, to check whether the variables really have the expected values.

  • Also watch out for invisible characters, like spaces. Chec, in the debugger, whether len(ly) (in the example) corresponds to what you would expect from the visible part.

  • I believe you didn't mention the version of Visual FoxPro, nor the service-pack you are using (if any). It is possible that some versions of Visual FoxPro have a flaw; but I consider this possibility remote in this case; at least, I didn't hear of version-specific problems for this particular command.
