Description Use this command to examine the RAM allocation and use for either static RAM or
NVRAM.
The Command displays:
• the memory block sizes
• whether they are used, and
• the total size of available free memory.
The command also queries the global memory RAM if in a multi-processor system.
Syntax Below is usage and syntax information for this command
Command Format CPM / D20 / D25: qr / (v | n)
CCU / CCUME: qr / (v | n | gv | gn)
Variables /v = volatile (static) RAM
/n = non-volatile RAM (NVRAM)
/gv = global volatile (static) RAM
/gn = global non-volatile RAM (NVRAM)
Parameters None
Example Type qr /gn and press ENTER.
Results: This displays the allocation and available free global
NVRAM.
The system displays the address and size of each
block in hexadecimal, the total free memory, and
number of free blocks in decimal notation before it
returns to the prompt.
Special
Considerations
Non-volatile memory cannot be queried if the NVRAM is
corrupt
