setTable(
modeNameString

of the parameter. Storing the previous setting
lets you restore it later.

is a character string that
specifies which parameter you want to set. It
must be one of the parameters from the table
below.
settingString
is a character string that
specifies the new setting for the parameter. It
must be one of the settings listed below for
the specific parameter you are setting.

setUnits()
CATALOG
setUnits(
list1
)
⇒
list
Sets the default units to the values specified
in
list1
, and returns a list of the previous
defaults.
•
To specify the built-in SI (metric) or
ENG/US system,
list1
uses the form:
{
"SI"
} or {
"ENG/US"
}
•
To specify a custom set of default units,
list1
uses the form:
{
"CUSTOM"
,
"
cat1
"
,
"
unit1
"
[
,
"
cat2
"
,
"
unit2
"
,
…
]}
where each
cat
and
unit
pair specifies a
category and its default unit. (You can
specify built-in units only, not user-defined
units.) Any category not specified will use
its previous custom unit.
All unit names must begin with an
underscore _.

setUnits({"CUSTOM","Length",

"Mass" "_kg" ...}
Note:
Your screen may display different
units.
•
To return to the previous custom default
units,
list1
uses the form:
{
"CUSTOM"
}
If you want different defaults depending on
the situation, create separate lists and save
them to unique list names. To use a set of
defaults, specify that list name in
setUnits()
.
You can use
setUnits()
to restore settings
previously saved with
setUnits()
! var
or with
getUnits()
! var
.
