To get a backreference in a REFind() you have to set the 4th attribute of
the function to true. Your function would then look like
sReference=REFind('(before)(HeresTheStringIWant)(after)',
myTargetString,1,1);
which says find the pattern in myTargetString starting with position 1 and
returning backreferences.
If it succedes, you will have a structure called sReferencethat contains 2
keys (pos and len). Each key is an array which contains the position (pos)
and length (len) of the data you want. Array element 1 is the entire pattern
return, element 2 is the first back reference, etc.
To get the second back reference use this:
Mid(myTargetString, sReference.pos[3], sReference.len[3])
