character in the Source container.

Parameters:

• Length: The number of characters to extract.
• Start: The character position in the Source container from which to extract

the characters.

ParseDelimited

The ParseDelimited rule extracts a specific substring from a delimited string.
A delimited string is a string made up of substring separated by a delimiting
character. For example: "this,is,a,comma,delimited,string".
This rule is useful in parsing comma-separated-value files.

Parameters:

• Delimiter: The delimiting character used to separate substrings.
• Index (optional): Which substring to extract.

Example:
If the BigString container contains "this=is=a=short=string" then the following
rule places "short" in the Token container.
