Using Local Variables in Functions or Programs
A local variable is a temporary variable that exists only while a user-defined function is
being evaluated or a user-defined program is running.
Example of a Local Variable
The following program segment shows a
For...EndFor loop (which is discussed later in
this module). The variable
i is the loop counter. In most cases, the variable i is used only
while the program is running.
NewPic Creates a picture variable based on a matrix.
Rename Renames a variable.
Unarchiv Moves specified variables from user data archive memory
to RAM.
Unlock Unlocks a locked variable.
