M55, Invalid nested ESTART command

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

During call back processing for events and prior to execution of a nested ESTArt command, the FOCUS display attribute for the display on which the window appears that is associated with the event being processed, must be assigned a value which identifies a window that has its MODAL window attribute equal to "APPLICATION". If the FOCUS attribute is not assigned such a value, this error will occur.

In earlier printed versions of the 1995 ANSI M[UMPS] Windowing Application Programmers' Interface, this error was identified as M?10.
