letfileglobal
VARIABLE
=
VALUE
The letfileglobal statement creates a fileglobal variable and assigns a value to it.
Parameters
This statement has two parameters:
variable – is the name of the variable that you want to create.
value – calculates the value that will be placed into the variable.
Description
This statement works just like an assignment, but the destination of the assignment is automatically created (if it does not already exist) as a fileglobal variable. For example, this statement creates a fileglobal variable named pageCount and assigns the value 23 to it.
letfileglobal pageCount=23
The value can be any data type, for example text like this:
letfileglobal userName="Bob"
Note: This statement is identical to the assignfileglobal statement, but letfileglobal uses an equal sign between the variable name and the value, instead of a comma.

- assign -- assigns a value to a field or variable.
- assignfield -- performs an assignment, much like an equals sign or the assign statement. However, the *assignfield* statement only performs the assignment to a database field, not to any variable.
- assignfieldwithsideeffects -- performs an assignment, much like an equals sign or the assign statement. However, the *assignfieldwithsideeffects* statement only performs the assignment to a database field, not to any variable. After performing the assignment, it will run any side effects associated with the field, including formulas and code associated with the field.

- assignglobal -- performs an assignment, much like an equals sign or the assign statement. However, the *assignglobal* statement only performs the assignment to a global variable.
- assignlocal -- performs an assignment, much like an equals sign or the assign statement. However, the *assignlocal* statement only performs the assignment to a local variable.
- assignwindowglobal -- performs an assignment, much like an equals sign or the assign statement. However, the *assignwindowglobal* statement only performs the assignment to a windowglobal variable.
- define -- performs an assignment, much like an equals sign or the assign statement. However, the *define* statement only performs the assignment if the variable is currently undefined. If the variable already has a value, the *define* statement leaves it alone. The *define* statement is especially useful for initializing permanent variables.
