GET
(KMON)
Loads a memory image file into memory.
Format
GET filespec
Parameter
filespec
Specifies the memory image file to be loaded. The default file type is SAV. Note
that a magtape is not a block-replaceable device and therefore is not permitted
with the GET command.
Description
Use the GET command for a background job only. The GET command is useful when
you need to modify or debug a program.
• Use GET with the Base, Deposit, Examine, and START commands to test
changes. Use the SAVE command to make these changes permanent, except
for a virtual program.
• Combine programs by issuing multiple GET commands, as the following example
shows. This example loads a program, DEMOSP.SAV, loads ODT.SAV (on-line
debugging technique, described in the RT–11 System Utilities Manual), and starts
the program using the address of ODT’s entry point:
.GET DEMOSP
.GET ODT
.START
ODT V05.6
*
Using the GET Command to Overlay a Previous Program
• If more than one program requires the same locations in memory, the program
you load later overlays the previous program.
• Note that you cannot use GET to load overlay segments of a program; it can load
only the root.
• If the file you need to load resides on a device other than the system device, RT–11
automatically loads that device handler into memory when you issue the GET
command. This prevents problems that occur if you use the START command
and your program is overlaid.
