| Syntax |
identifier = expression
|
| Action |
Evaluates expression and assigns the resulting value to identifier.
|
| Examples |
local (x); x = 3 * 4 » 12
The assignment statement causes the value of the expression "3 * 4" to be stored in the local variable "x".
In this case the expression "clock.now ()" yielded a date value, which was then assigned to the cell named "when" in the table named "scratchpad." (The "when" cell need not have already existed.)
In this case, we copy a value out of the object database and store it in a local variable. |
| Notes |
The identifier need not specify an existing database cell; the assignment statement will create an item with the given name in the specified table. If no table is specified, a new local variable is created in the code block where a local statement or a local script definition was most recently encountered. While assigning values to variables without declaring them can be a timesaver, it is generally bad practice; as a script becomes more complex, it quickly becomes easy to unintentionally modify a variable in an enclosing scope level.
