Delete a global user variable

[cyrille de brébisson]

Hello,

They are a lot of different types of variables in Prime.
non CAS:
- variables ALWAYS have a value.
- you can NOT use a variable which does not exists.
- some variables have enforced types (A-Z, Z0-Z9, L0-L9, M0-M9)
- You have a number of pre-existing global variables which can not be erased (system variables)
- You have a number of pre-existing app specific variables (xMin...) which can not be erased
- you can create user variables by doing varName:=value (or value|>varname). These variables can be erased through the memory manager (backspace)
- you can create new app specific variables (user visible or not) by attaching a program to an app (EXPORTed variables will be user facing and apear in menus). to delete these variables, you need to remove them from the program definition
- you can create new global user variables (user visible or not) by creating a program (EXPORTed variables will be user facing and apear in menus). to delete these variables, you need to remove them from the program definition.


Then you have CAS variables! create them by doing a sto operation and erase them either through purge command or the memory manager.
