WINDOW real-valued function BELT.MODE system parameter.) 1. If the value of the mode expression is less than or equal to zero (the default), the value returned is interpreted as follows (see the following figure): 0 The location is outside the window. The location is inside the window, closest to the downstream window boundary; the distance is ABS(value_returned). >0 The location is inside the window, closest to the upstream window boundary; the distance to the boundary is the returned value. WINDOW Function for Mode 2. If the value of the mode expression is greater than zero , the value returned is interpreted as follows (see the following figure):
0 Indicates the location is within the window. Indicates the location is upstream of the upstream window boundary; the distance is ABS(value_returned). >0 Indicates the location is downstream of the downstream window eV+Language Reference Guide, v2.x, 18319-000 Rev A Page 570
