FindStringByStarting&EndingChar (FSTR)
This function has the following syntax:
FSTR<source_string, string_start, string_stop, mode>string
This function searches for a substring having a defined starting character ("string_start") and a
defined ending character ("string_stop") within the "source_string". It returns the string you
searched for, or an empty one in case of failure.
If searching for a substring having characters already known, the "string_start" and
"string_stop" arguments must share the same value.
The "mode" argument allows managing the starting character ("string_start") and the ending
character ("string_stop"):
0 = include both starting and ending character
1 = include only starting character
2 = include only ending character
3 = discard both starting and ending character
