There are two types of Watch command available:

Watch command without a task name shows the value of any expression.

Watch command with a task name only exhibits the value of global variables addressed by the task, or static variables declared within the task.

Syntax

Watch <expression>

Watch <task name> <variable_name>

Availability

All versions

Scope

Task or Terminal

Limitations

Watch command without a task name cannot be used for function calls.

In Watch command with a task name, the task must exist and must be stopped. Global variables must be approched by the task.

Examples

MyTask.Prg:

dim shared stat_var as double = 54.76

Watch glob_var 
Watch sys.idn[1]

Watch MyTask1.prg stat_var
