There is a simple trick that you can use to get the "idea" of comments into the #Define mechanism.
In the "Label Name" column use a label that is prefaced by two underscore characters, "__". This character pattern is not, typically, used in TBASIC so it will not be an issue.
You can then either leave the "Variable" column blank or you can enter more information into this field to add to your comment.
The attached jpg is shows how I use the "__" trick to remind me of the purpose of the #Defines.
My wish for the #Defines is to extend the idea to allow parameterized macros and to allow a macro to reference an existing macro. The "C" pre-processor supported these behaviors.
