getMode() CATALOG
getMode( modeNameString )
⇒ ⇒ ⇒ ⇒ string
getMode("ALL ") ⇒ ⇒ ⇒ ⇒ ListStringPairs
If the argument is a specific mode name, returns
a string containing the current setting for that
mode.
If the argument is "ALL" , returns a list of string
pairs containing the settings of all the modes. If
you want to restore the mode settings later, you
must store the
getMode("ALL") result in a
variable, and then use setMode() to restore the
modes.
For a listing of mode names and possible settings,
see
setMode() .
Note: To set or return information about the
Unit System mode, use setUnits() or getUnits()
instead of setMode() or getMode() .
