I think it's weird. :-)

I have not seen this issue previously, but I don't know if I've ever used DTOC() on datetime.

I probably would've used:

SUBSTR(TTOC(ltWhatever),7,4) + LEFT(TTOC(ltWhatever),2) + SUBSTR(TTOC(ltWhatever),4,2)

because I didn't know about the extra flag in TTOC() LOL! So, it likely would not have been an issue. :-)

I am curious if you use:

INDEX ON LEFT(TTOC(ltWhatever),10) TO whatever.cdx TAG whatever FOR status = '5'

if it does the same thing in VFP9SP1?
