WinName A
string literal (without quotes) representing the name of a window,
or an at-sign followed by the name of a local variable (@name)
where the value of that variable is expected to be equal to the
name of a window at run-time.
If missing, the default is the current window.
CtlName A string literal (without quotes) representing the name of a control, or an at-sign followed by the name of a local variable (@name) where the value of that variable is expected to be equal to the name of a control at run-time.
The macro %%KillCtl should only be used for components in windows that were created by other software than the MSM ViEW-Builder, e.g. by directly merging structures into ^$Window, or by using the macro %%MergeCtl.
