dev_inspect_ctrl — Open a window to inspect one or more control variables.
dev_inspect_ctrl( : : Variable : )
dev_inspect_ctrl opens a variable inspect dialog to display the
contents of one or more control variables. The result of this action is
identical to selecting Inspect from the context menu of control
variables in the variable window.
The standard inspection window displays the variable values with some optional
statistics in a table. The window title is generated from the given parameter
names. For some semantic types a special representation
exists, e.g., functions are displayed as function plot by default. For more
information, see the chapter “Inspecting Variables” in the
“HDevelop User's Guide”.
You can pass a tuple of variables in Variable to open an
inspection window for multiple variables. It is also possible to override
the default inspection mode by including a string literal as the first
element of the tuple:
Show the values in the default inspection window even if the semantic type of the variable has a special representation.
Plot the values of numeric variables against their tuple index.
Plot the values of numeric variables as X-Y pairs. The number of variables must be even, with each pair of variables having the same length.
Note that no expressions are evaluated inside the call of
dev_inspect_ctrl, but only the contained parameter names are parsed.
Therefore, operations like, e.g., accessing a specific tuple range
or arithmetic tuple operations need to be done beforehand.
Normally, the window contents will be updated whenever the variables
change. However, the update behavior can be influenced by the operator
dev_update_var and the Update Variable preference.
The dialog can be closed by pressing the Close button or by calling
dev_close_inspect_ctrl.
This operator is not supported for code export.
Variable (input_control) integer(-array) → (integer / real / string)
Name of the variable to be checked.

If the values of the specified parameters are correct,
dev_inspect_ctrl returns TRUE. Otherwise, an
exception is raised and an error code returned.
