Instruction substring

Overview

This method performs a substring operation on either a question value or the input value.

Question Id

Optional. You can specify a question path, when the instruction should work on a question value.

Value

A comma separated list, whose first entry is either “begin” or “end”. If it is “begin”, then two more values are required: start index and end index. If the first entry is “end”, then only one additional entry for the number of characters is required.
Example: Assume the input or question value is “ABCDEF”. A substring instruction with value “begin,0,4″ would return “ABCD”. A substring instruction with value “end,4″ would return “CDEF”.

Input value

The input value is used, when no question is specified.
