* contrib/hbfoxpro/hbfoxpro.hbx
* contrib/hbfoxpro/occurs.prg
+ added FoxPro compatible At() function with 3-rd <nOccurrence>
parameter:
fox_At( <cSubstr>, <cString>, <nOccurrence> ) -> <nPos>
* contrib/hbfoxpro/hbfoxpro.ch
+ added PP rule for At() with FoxPro like 3 parameters,
please remember that such At() extension is not compatible with
xHarbour one so do not include hbcompat.ch or xhb.ch - they
redefines At() with 3 or more parameters to xHarbour compatible
function: hb_At()
