How to pick a shorter substring out of a long string in SCC?

If I have a string in a variable [u:df96ee5a3a]cline[/u:df96ee5a3a], whose value is 'Now is the time for all good men', is there a way I can assign characters 7 thru 18 into another string variable, so the new (shorter) variable gets the value 'the time for' ?

Is there a place where such functions are documented? I've found the functions whose names start with [u:df96ee5a3a]str[/u:df96ee5a3a] easily enough, in the HELP section for SCC.

strncpy

[u:794fd2938e]strncpy[/u:794fd2938e] takes the FIRST characters found in a string, not characters from somewhere in the middle of the string, correct?

You can add an integer offset to the char* pointer in order to point to the first position from which to copy.

This will have to be my last post on this subject. This is not really the place to get help with elementary programming.
