Code to control scheduled script

[Mirco]

Hi, now it's been an hour that I am searcing in the forum, but I' was not able to find what I need.

I would like to:

1. Create a scheduled script and set all parameters: name, hour and minute, day, month, day of week, active/not active, category and description
   
2. Modify a scheduled script and set all parameters: name, hour and minute, day, month, day of week, active/not active, category and description
   
3. Delete a scheduled script
   

someone can answer with all this codes so that we have one thread with all the codes for control scripts?

Thank you very much!
