Programmable Operator Rolling Console Facility for Virtual Machine

Function:

PROPROLL is a VM/CMS based facility that provides the VM operator with a console that not only captures all messages directed to it, but presents the messages in a "rolling" fashion.  All messages enter from the bottom and progress to the top of the display.  

Messages that move off the top of the display are re-viewable by scolling back the screen using the PF keys to control backward and forward motion.

This program was designed to be used in conjunction with IBM's Programmable Operator Facilty (PROP).  PROP would run in a disconnected mode on the Operator virtual machine. The machine that PROPROLL executes would act act as the Logical Operator as designated by the Routing Table of the PROP.  All messages would be routed to the Logical Operator that would act as the message and control focal point for VM Operations.

This mode of operation has several advantages:

• The user would never have to clear a "MORE...'  or  'HOLDING..' condition
• each time that the console filled with messages.
  
  
• The user is able to scroll back, currently for 3000 lines, to any messages 
• that have already rolled off the screen.
  
  
• Messages that a pending to be displayed are held while the program is in
• scroll mode.   A flag indicating pending messages is signalled to the user.
  
  
• Commands can be issued to either the Logical Operator or the System Operator
• by way of the OP and CP commands.
  
  
• The last 50 commands are saved and can be redisplayed with a PF key.
