Functions Index :: S :: StrMid
StrMid(string s, int start, int "length")
A replacement of MidStr standard Avisynth function. For Avisynth versions up to 2.55 offers the ability to handle twice as large strings than the standard function; for later versions it has the same functionality.
The arguments are those of the associated standard Avisynth function.
s1 = StrMid("\avisynth", 1, 5)
s2 = StrMid("\avisynth", 6, 3)
# s1 == "avisy", s2 == "nth"
