Substring - Novell POLICY IN DESIGNER 3.5 - 09-18-2009 Manual

Substring

Extracts a portion of the enclosed tokens.
Fields
Start
Specify the starting character index:
Index 0 is the first character.
Positive indexes are an offset from the start of the string.
Index -1 is the last character.
Negative indexes are an offset from the last character toward the start of the string.
For example, if the start is specified as -2, then it starts reading at the first character from the
end. If -3 is specified, then is starts 2 characters from the end.
Length
Number of characters from the start to include in the substring. Negative numbers are
interpreted as (total # of characters + length) + 1. For example, -1 represents the entire length of
the original string. If -2 is specified, the length is the entire string -1. For a string with 5
characters, a length of -1 = (5 + (-1)) + 1 = 5, -2 = (5 + (-2)) + 1 = 4, etc.
