String components

These process one or more status string inputs, and produce some form of output.

String object types vary by type of output. Three string components perform a string function with a StatusString output:

• StringConcat

• StringSubstring

• StringTrim

Two string components provide a logic function with a StatusBoolean output:

• StringIndexOf

• StringTest

StringLen provides a StatusNumeric output equal to the number of non-null characters in the input string.
