Can I have some timings, please?

1003 µs for loading 26902 lines into a string array

1543 µs for finding 1074 matches, old MB Instr

2099 µs for finding 1074 matches, Masm32 find$
2085 µs for finding 1074 matches, Masm32 find$

P.S. Masm32 find$() returned "wrong" results until I realised that eax must be positive for a match. So the correct use is this:

Code Select
.if sdword ptr find$(1, pSource$, pFind$)>0
inc esi
.endif
