How to create a legend ?

The command KEY is designed to create a legend with a marker type. Since the version 2.07 of PAW this command has been expanded, and allows to produce legends with lines and filled areas. For the PAW versions before 2.07 a macro similar to the following one can be used:

 Macro Legend
 TYPE = [1]   | Type of hatches
 X1   = [2]   | X bottom left corner of the box.
 X2   = [3]   | X top right corner of the box.
 Y1   = [4]   | Y bottom left corner of the box.
 Y2   = [5]   | Y top right corner of the box.
 TEXT = [6]   | Text to be printed
 Set FAIS 3
 Set FASI [TYPE]
 Set BORD 1
 Box [X1] [X2] [Y1] [Y2]
 Set TXAL 03
 XT = [X2]+$GRAFINFO('?CHHE')
 YT = ([Y2]+[Y1])/2
 Itx [XT] [YT] [TEXT]
 Return

Note that this kind of macro is anyway useful to personalise an output.
