Numeric parameters are vectors of 16 real elements. During the definition of the parameter, a lower bound and upper bound are specified which define the range of values the elements may take. An attempt to assign a value outside of this range to an element would result in an error.
Elements which have never been assigned a value are said to be "missing" or undefined. Elements may be missing elements as a result of an assignment or LET command. For example, the following sets the first two elements of VECTOR to 1 and 2, and the other 14 values to "missing".
EASI>VECTOR=1,2
During parameter definition, a default value is also specified. (This value may or may not be in the range allowed by the upper and lower bounds). During the execution of application tasks, this default is used for missing elements.
