The OPS8000 can use battery backup RAM chips as well as static RAM and EPROMS.
This allows for variables to retain their value after power is removed from the OPS. This also allows for programs to be retained without use of EPROMS. The battery backup RAM has an approximate life of 7 to 10 years.
To pass a variable to a global variable on the ACR card, after serial communication is set up between the OPS and the ACR controller, send the value by using a print command.
IF a print command is made from the OPS8000 to the open port it will assign that value like entering an immediate mode command
100 PRINT #1,"P0=";P0
or using an array entry
100 PRINT #1,"P0=";P0(0)
