DEVOUTPICT()
 Write a value to the current device using a picture clause
------------------------------------------------------------------------------
 Syntax

     DEVOUTPICT(<exp>, <cPicture>, [<cColorString>])
        --> NIL

 Arguments

     <exp> is the value to display.

     <cPicture> defines the formatting control for the display of <exp>.
     The picture specified here is the same as one used with @...SAY or
     TRANSFORM and can include both templates and functions.

     <cColorString> is an optional argument that defines the display
     color of <exp>.  If the current DEVICE is SCREEN, output displays in the
     specified color.

     If not specified, <exp> displays as the standard color of the current
     system color as defined by SETCOLOR().  <cColorString> is a character
     expression containing the standard color setting.  If you want to
     specify a literal color setting, it must be enclosed in quote marks.

 Returns

     DEVOUTPICT() always returns NIL.

 Description

     DEVOUTPICT() is a full-screen display function that writes the value of
     a single expression to the current device at the current cursor or
     printhead position.  DEVOUTPICT() is used in combination with DEVPOS()
     in Std.ch to implement the @...SAY command used with a PICTURE clause.

 Examples

     .  This example shows the relationship between the DEVOUTPICT()
        function and the @...SAY command:

        DEVPOS(10, 10)
        DEVOUTPICT("Hello there", "@!", "BG+/B"))
        //
        @ 10, 10 SAY "Hello there" PICTURE "@!" COLOR "BG+/B"
