Configuration commands

This section describes commands that allow you to configure the virtual machine behaviour. This configuration is stored in the MDK directory ~/.mdk.

As you can see in their description, some commands print, as a side effect, informational messages to the standard output (e.g. load prints a message telling you the loaded program's start address): these messages can be enabled/disabled using slog:

slog on|off config command
Turns on/off the logging of informational messages. Note that error messages are always displayed, as well as state messages required using commands prefixed with p (preg, pmem and the like).

stime on|off config command
ptime config command
The stime command (un)sets the printing of timing statistics, and ptime prints their current value: 
          MIX > ptime
          Elapsed time: 10 /Total program time: 11 (Total uptime: 11)
          MIX >

sedit TEMPLATE config command
pedit config command
sedit sets the command to be used to edit MIXAL source files with the edit command. TEMPLATE must contain the control characters %s to mark the place where the source's file name will be inserted. For instance, if you type 
          MIX > sedit emacsclient %s
          MIX >

issuing the mixvm command edit foo.mixal will invoke the operating system command emacsclient foo.mixal.

pedit prints the current value of the edit command template.

sasm TEMPLATE config command
pasm config command
sasm sets the command to be used to compile MIXAL source files with the compile command. template must contain the control characters %s to mark the place where the source's file name will be inserted. For instance, if you type 
          MIX > sasm mixasm -g -l %s
          MIX >

issuing the mixvm command compile foo.mixal will invoke the operating system command mixasm -g -l foo.mixal.

pasm prints the current value of the compile command template.

sddir DIRNAME config command
pddir config command
MIX devices (see Devices) are implemented as regular files stored, by default, inside ~/.mdk. The sddir command lets you specify an alternative location for storing these device files, while pddir prints the current device directory.

Finally, you can change the default command prompt, MIX > , using the prompt command:

prompt PROMPT config command
Changes the command prompt to prompt. If you want to include white space(s) at the end of the new prompt, bracket prompt using double quotes (e.g., prompt ">> ").
