hello JD,
add
{$DEFINE USE_SOROKINS_REGEX}
( which enables the unit regexpr coming with fpc. )
at the beginning of the file because maybe you have'nt the sources of FLRE regexpr.
You need the sources of the other regexp units to enable them. (dregexpr.pas is in the folder of internetTools
import\regexpr\source).
Friendly, J.P
