^not(condition)^
If the condition is true, ^not(condition)^ is false. This has limited usage, inside an ^if(condition)^ statement to reverse the boolean result of the test. For example:
^if(^nextSibling^)^Yes^endIf^ will insert the text 'Yes' if there is a next, exportable, sibling. To reverse this it is possible to reverse the test and place the insertion in the logical 'else' branch:
^if(^nextSibling^)^^else^Yes^endIf^ But use of ^not()^ can give more easily understandable code:
^if(^not(^nextSibling^)^)^Yes^endIf^ Note how the code wraps the condition inside the ^if()^.
The ^not()^ code should not be used for negating condition queries written fully in action code syntax. So do not use a mix like:
^if(^not($MyString=="")^)^Yes^endIf^
Instead, use:
^if($MyString!="")^Yes^endIf^ In summary, this is a niche code that you should not expect to need except with export codes that are fixed boolean assessments and are being used in export code form in a condition argument. Most likely use is with testing ^previousSibling^ and ^nextSibling^ state.
