☜	Error Code M51 M[UMPS] by Example					☞

M51, Attempt to destroy M-Term window prior to CLOSE

Introduced in the 1995 ANSI M[UMPS] Windowing Application Programmers’ Interface.

If the device specified in a Close command designates an MTERM window that was created by the execution of an Open command, the window in question will be destroyed.
If the device specified in a Close command designates an MTERM window that was created by the assignment of values to attributes in structured system variable ^$Window, the Close command will not cause the window to be destroyed, and this error will occur. For this error, there is no corresponding value in special variable $ERef.

In earlier printed versions of the 1995 ANSI M[UMPS] Windowing Application Programmers’ Interface, this error was identified as M?6.
