4.26 FAQ-385 What is Substitution Notation?SubstitutionNotation
Last Update: 3/31/2023
When a script is executed, the LabTalk interpreter searches for two types of special substitution notation which are identified by the initial characters of % or $. These are then sent to the substitution processor, which replaces the original string with another string.
There are four types of run-time substitutions:
String register substitution %A - %Z, etc.
%( ) Substitution, a powerful notation to resolve %(str$), %(range), worksheet info and column dataset names, worksheet cells, legends, etc.
$( ) Substitution, where $(expression) resolves the numeric expression and formats the result as a string.
%n Macro and Script substitutions of the form %n, where arguments are passed to a macro or a script.
Please see the Substitution Notation for more details and examples.
