View
The VIEW command displays trace A, B, or C, and stops the sweep. Thus, the trace is not updated. Trace A and
C are discussed below. For detailed information about trace B. see B3 in this section.
When VIEW TRA is executed, the contents of trace A are stored in display memory addresses 1 through 1023.
Address 0 is reserved for the instruction word 1040'. Similarly, when VIEW TRC is executed, the contents of trace
C are stored in display memory addresses 3073 through 4095, and address 3072 is reserved for the instruction
work 1048'. Therefore, any information stored in address fJ is lost when VIEW TRA is executed. Likewise, the
contents of address 3072 are lost when VIEW TRC is executed.
If you have used address 91 or 3072 for a graphics program, or label, you may wish to save their contents before
executing VIEW.
