If I have a string containing 25 characters, how do I extract the eight characters starting at position 5 in the string?

This should be a simple thing to do but I can't figure it out and can't figure out which dictionary item applies.
By the way, the exact phrase you needed was under "character" in the transcript dictionary. Did you look up "character"?
Possibly not - every other language I've used (somewhere beyond 20 of them professionally and a few more just to look at) has done this with either
a function - e.g. substr(name, start, end) or Sub(name, start, len)
or
a bit of punctuation e.g. name(5,8) or name[5:12] or ...
or
a method e.g. name.substr(5,8)
Some of them may have used character to extract a single character, but I can't think of another one that used the word "character" (or even characters) to extract a substring
and for many of them, searching their docs using "character" wouldn't have helped.
So maybe if I was less experienced, I'd have tried that first .... :-)
How quickly do you find the answer in the Rev docs by searching for substring section of a string part of a string string ...
