Host Mode

   If a mouse or Cyclops and a data cable are connected to the panel, it can also operate in the
   Host Mode. Host Mode can only be used when the panel's menu and LightBoard are not active.
   This means that the panel and its control devices are communicating directly with the host
   computer.

   In Host Mode, the projection panel mouse functions as the system mouse. It communicates with
   the computer and controls the screen cursor for all computer functions.

   ·         If the projection panel's I/O port is sensed first during the computer's start-up,
   the projection panel mouse becomes the system mouse and the computer mouse is not seen.

   ·         If the computer mouse is seen first and the user wants the panel mouse to be the
   system mouse, the user must switch the mouse and projection panel ports and restart the
   computer.

   ·         If you are in Host Mode and the panel menus or LightBoard are selected, the
   projection panel mouse is forced to Local mode operation until those functions are turned off.

   Please refer to the Cyclops 2050 User Guide for projection panel Host Mode mouse operation
   with a Cyclops module installed.

   2. String functions

   

   String functions may be used both as operands of string expressions' and as formatting
   commands. When used as a command, the function value will be formatted as if it was a field in
   the record.

   

   F(expr-l,expr-2,expr-3)

   

   The F function converts a numeric value from its internal floating point representation to a
   character string. The three arguments are all numerical expressions. The first argument,
   expr-1, is the number to be converted. The second argument, expr-2 is the minimum output width
   and the third argument txpr-3 is the number of decimal places.

   

   The second and third arguments are optional. Note, however, that expr-2 cannot be omitted if
   expr-3 is present.

   

   expr-2 gives the minimum width, i.e. the function value will be a character string of at least
   expr-2 characters and, if the converted numerical value requires expr-2 characters or less, it
   will be right adjusted within this width. If the number of characters required to represent
   the value of expr-1 is greater than the width given, then CDS/ISIS will use additional
   character positions as needed. In this case the output string will be longer than expr-2
   characters.

   

   expr-3 defines the number of decimal places. If missing, the result will be in scientific
   exponent notation and, if also expr-2 is missing a default width of 16 characters will be
   used. If present, the result will be a rounded fixed point representation of expr-1 with
   expr-3 digits after the decimal point. If expr-3 is zero then expr-1 is first rounded toward
   the nearest integer and output as an integer value with no decimal point.

   For fixed point and integer conversion, if the integer part of the number is too large to be
   represented, the output is replaced by a series of asterisks (1).

   The F function may be used to align a column of numbers on the decimal point by choosing an
   appropriate with.
