Variable Declaration

Action

Declares a variable.

Syntax

[scope] [share] data-type variable-id [ = expr ] [, variable-id [ = expr]] ...

Variable	Description
`scope`	Optional: Either public (the default) or private. Private declarations are available only in the file in which they occur. Public declarations can be accessed from other files through a use statement. You can specify the scope only if the declaration is global, which means that the declaration is not located within a function, a window, or a winclass declaration.
`share`	Optional: Indicates that the variable is shared by multiple threads. Access to shared variables is controlled with the access statement.
`data-type`	The data type of the variable.
`variable-id`	An identifier that specifies the name of the variable.
`expr`	Optional: An expression that evaluates the initial value of the variable. The value must be compatible with the type of the variable. If you try to use a variable before the value of the variable is set, 4Test raises an exception.

Notes

To pass global variables between .t files in a project, declare the variables in the frame.inc file of the project.
If your scripts spawn multiple threads for parallel processing, keep in mind that all threads have equal access to global variables. To prevent multiple threads modifying a variable at the same time, declare the variable as shared, using the share keyword. A thread can request access to shared variables using the access statement.
Concurrent access to a local variable or a non-shared global variable by parallel threads might generate unpredictable results. Use shared variables wherever the potential for conflict exists.
