Image; Incr; Indep - HP 48gII Advanced User's Reference Manual

If the argument is an array, IM returns a real array, the elements of which are equal to the
imaginary parts of the corresponding elements of the argument array. If the argument array is
real, all of the elements of the result array are zero.

INDEP

Type: Command
Description: Independent Variable Command: Specifies the independent variable and its plotting range.
The specification for the independent variable name and its plotting range is stored as the third
parameter in the reserved variable PPAR. If the argument to INDEP is a:
• Global variable name, that name replaces the independent variable entry in PPAR.
• List containing a global name, that name replaces the independent variable name but leaves
unchanged any existing plotting range.
• List containing a global name and two real numbers, that list replaces the independent
variable entry.
• List containing two real numbers, or two real numbers from levels 1 and 2, those two
numbers specify a new plotting range, leaving the independent variable name unchanged.
(LASTARG returns a list, even if the two numbers were entered separately.)
The default entry is X.
