MidString

Action script to extract part of a string from a route variable.

Example:

The following example will take the last three digits from the variable 'nj.Source' and store them in the variable 'targetExtension'.

The Route Variable nj.Source contains '0383208100'.

The MidString step is configured as:

Input: nj.Source
Start index: 7
Length: 3
Output: targetExtension

The result is that targetExtension will contain the value '100'.

 Input

Takes name of a variable containing the value to extract a sub string from.

Start index

The index into the Input string to start  from.

The value must be zero or greater.

The value must be no more than the length of the input string.

The index is zero (0) based.

So if you want the first character of the input then you should specify:

Start index: 0

Length: 1

Length

The number of characters to extract. If the Start Index + Length goes off the end of the string then a result will still be returned but it will be less than the desired length.

Output

The name of the Route Variable the resulting value is stored into.
