One of those trivial things we do when programming is declaring (a lot of) variables. We made the Variable and Constant Builders and the declaration shortcuts simply as time savers. Time consuming in declarations are:
Declaration shortcuts ('Fast Declare', e.g. Alt-CVS to declare a local Variable of type String) are used most often. They work very simple, just enter the name and the declaration is added at the top of the procedure. Additionally the variable is available in memory to Paste (Ctrl-V).
The Builders are used for all other cases, such as when you want to declare object type variable or to make a global constant declared in a dedicated constants module (saves you switching back and forth between modules).
