Logic tells me that ALLTRIM does two internal calls to the same functions that LTRIM and RTRIM use. This makes each ALLTRIM twice as long as an LTRIM. Therefore, when using numerics, LTRIM is twice as fast! Same with ATC() when you know both elements are the same case (or searching for non-alpha characters) - use AT() instead.

When you work with large scale systems such as my current contract, every single instruction needs to be evaluated for speed. It's also one of the habits I forced myself to use some years ago (along with specifying SHARED or EXCL when opening tables, among others).
