If you want to restrict the user of your HyperCard stack to the browse level
while the script is allowed to modify the stack, take note of the following
scripts:
1. This script stores the Home card userLevel in the global variable
"Store_userLevel" and sets the userLevel to 1 (Browsing). When
quitting the stack, you may restore the userLevel to the value in
"Store_userLevel".
on openStack
global Store_userLevel
put the userLevel into Store_userLevel
set the userLevel to 1
end openStack
2. This script shows how to change the userLevel, so modifications can be
made to the stack via HyperTalk commands.
on mouseDown
set the userLevel to 5
-- (Do stack modifying commands here)
set the userLevel to 1
end mouseDown
3. This script shows how to use the "cantmodify" property to prevent a user
from modifying a stack while still allowing the script to do so.
on openStack -- (Put this in the stack script)
set cantModify to true
end openStack
on mouseDown
set cantModify to false
-- (Do stack modifying commands here)
set cantModify to true
end mouseDown
