- Processing starts with the independent variable value given by
- START+BIAS and continues until a value at or beyond START+BIAS+DUR is
- reached. When interpolation mode is enabled, the STEP control
- determines the value for successive processing points (called the 'step
- value' or 'step time'). The number of data points processed is
- DUR/STEP + 1.
-
- When interpolation mode is disabled, processing takes place only at the
- data points contained in the data file(s) being processed. The step
- time is reset at each processing point to the value taken from each
- file being processed. Multiple data files may be processed in
- expressions, but they must have the same step times; otherwise the
- value calculated for the expression may be meaningless. (See the
- INTERP control description.)
