IMS-7040-00-E (TP) Screen must be labeled

SCRNLIST supplied the name of a screen without the LABELED option, where the input message contains the screen name as the final 8 bytes. AMB requires this so that logic generated by SCRNLIST can determine which screen it received at run time.
Restriction: This topic applies only when the AppMaster Builder AddPack has been installed, and applies only to Windows platforms.

Resolution:

Verify that you provided the correct screen names to the SCRNLIST call. If necessary, specify the LABELED option and regenerate the screens that do not specify this option.
