result = lenstr(str)
ROUTINE: lenstr USEAGE: result=lenstr(str) input: str a single string or string array. output: result length of the string(s) in normalized units the number of elements of RESULT matches the number of elements of STRING. procedure: This function returns the physical length of the string on the output device, not the number of characters. This is done by first switching to 'X' and writing the string(s) with XYOUTS in graphics mode 5, which disables display to the screen but does not interfere with operation of XYOUTS. The WIDTH keyword parameter of XYOUTS is used to retrieve the physical length of the string(s). author: Paul Ricchiazzi 7apr93 Institute for Computational Earth System Science University of California, Santa Barbara
