Good Evening - just thought I'd document a work-around that I've been working with over the last year or so.
In the script editor - when creating a script - if you create a new script - and add parameters to the script - and then press 'Save" - you would normally assume that the script and the parameters you created for the script - would be saved.
This expected functionality - is not what happens. If you are editing a script - and during development - add params that the script will need when called - these are not saved by pressing save 
(they disappear if you press save - and then go over to the database or application editor - or just plain fall asleep in front of your work --- that never happens 
)
In order for the parameters to save - you must press "Save and Run" - sometimes (ok - often times) I am hesitant to run a script under development - until I can create some test data, etc. and have good logging - and forcing a run - in order to save the parameters - generally not good practice. As a workout I intentionally create a syntax error in the script at the top of the script - to ensure it won't compile and run until I'm ready - but still take advantage of the need to save parameters during script development.
Happy Tuesday,
Bruce
