;*THIS PROGRAM PROVIDES THE PROGRAM LOADING CAPABILITY FOR PDP-10
;*DIAGNOSTICS. PROVIDES FOR LOADING AND RUNNING SINGLE DIAGNOSTICS OR
;*CHAIN EXECUTION OF A SERIES OF DIAGNOSTICS.
;*THIS PROGRAM WILL EXECUTE PDP-10 DIAGNOSTICS AND RELIABILITY
;*PROGRAMS THAT ARE CAPABLE OF BEING RUN UNATTENDED.
;*RUNS ON KL10, KI10 & KA10 PROCESSORS
;*IT PROVIDES FOR CONTINUOUS TESTING FOR EQUIPMENT CHECKOUT
;*AND/OR FAST ITERATION OPERATION FOR MARGIN TESTING.
;*ALSO PROVIDES SPECIAL USER MODE OPERATION FOR KL10 & KI10
;*AND MARGIN OPERATION FOR KI10.
