Variables
  --clear=name[:scope] (clear a variable)
    scope of variable is optional - can be global, bank or drive.  drive is default
    it determines which other ULCLI processes handling other drives can see the variable.
  --clearall[=scope] (clear all variables, default scope is drive)
  --set=varname:value[:scope] (set a variable)
* --varname=value (special shortcut for --set=varname:value, always in a scope of 'drive')
    Any variable set via the above two methods can be used by enclosing in curly braces.
    e.g. --set=inputstack:2:global
    e.g. --command=_MOVE{inputstack}:$S.{inputstack}:15:5
    e.g. --notify="An error occurred loading from stack {inputstack}."
    You can also also return a subset of the variable: {VARNAME,START,LENGTH}.
    e.g. --notify="An error occurred loading from drive letter {drive,1,1}."


Implicitly set Variables (that is, set by ULCLI)
  {drive} = drive letter
  {drivebank} = drive bank (1 or 2)
  {comport} = e.g. COM2
  {notifyreturncode} = button pressed by operator during last --notify= call


Complex Flow of Control using Variables
  --ifsetskip=name:value:sv[:scope] (use variables as execution conditionals)
  --ifnotsetskip=name:value:sv[:scope] (use variables as execution conditionals)


Notifications
  --notify=message[:title[:type[:timeout]]] (notify operator with message and beep)
    Message and Title are double quote-enclosed strings (no colons allowed), timeout is in s)
    Button press sets the variable {notifyreturncode})
    Types can be:
      0 - OK
      1 - OK and Cancel (the default)
      2 - Abort, Retry, and Ignore
      3 - Yes, No, and Cancel
      4 - Yes and No
      5 - Retry and Cancel
      6 -  Cancel, Try Again, Continue 
    The {notifyreturncode} set by Operator's button press will be:
      1 - OK
      2 - CANCEL
      3 - ABORT
      4 - RETRY
      5 - IGNORE
      6 - YES 
      7 - NO
      10 - TRY AGAIN
      11 - CONTINUE
  --beep[=*blooper*] (*blooper* is hertz)
* --messagefile=filepath in quotes (used to send messages back to calling programs)
  --message=text in quotes (written to the file specified in messagefile)
