You have at your disposal a series of commands that let you load and execute MIX executable files, as well as manipulate MIXAL source files:
load file[.mix] | file command |
This command loads a binary file, file.mix into the virtual
machine memory, and positions the program counter at the beginning of
the loaded program. This address is indicated in the MIXAL source file
as the operand of the END pseudoinstruction. Thus, if your
sample.mixal source file contains the line:
END 3000 and you compile it with MIX > load sample Program loaded. Start address: 3000 MIX > |
run [file[.mix]] | file command |
When executed without argument, this command initiates or resumes
execution of instructions from the current program counter
address. Therefore, issuing this command after a successful load ,
will run the loaded program until either a HLT instruction or a
breakpoint is found. If you provide a MIX filename as argument, the
given file will be loaded (as with load file) and
executed. If run is invoked again after program execution
completion (i.e., after the HLT instruction has been found in a
previous run), the program counter is repositioned and execution starts
again from the beginning (as a matter of fact, a load command
preserving the currently set breakpoints is issued before resuming
execution).
|
edit [file[.mixal]] | file command |
The source file file.mixal is edited using the editor defined in
the environment variable MDK_EDITOR. If this variable is not set,
the following ones are tried out in order: X_EDITOR, EDITOR
and VISUAL. If invoked without argument, the source file for the
currently loaded MIX file is edited. The command used to edit source
files can also be configured using the sedit command
(see Configuration commands).
|
compile file[.mixal] | file command |
The source file file.mixal is compiled (with debug information
enabled) using mixasm . If invoked without argument, the source
file for the currently loaded MIX file is recompiled. The compilation
command can be set using the sasm command (see Configuration commands).
|
pprog | file command |
psrc | file command |
Print the path of the currently loaded MIX program and its source file:
MIX > load ../samples/primes Program loaded. Start address: 3000 MIX > pprog ../samples/primes.mix MIX > psrc /home/jao/projects/mdk/gnu/samples/primes.mixal MIx> |
Finally, you can use the quit
command to exit mixvm
:
quit | file command |
Exit mixvm , saving the current configuration parameters in
~/.mdk/mixvm.config .
