4: --------------------------------------------------------------------------*\ * main * * Displays the entire "plpoin" symbol (font) set. \*--------------------------------------------------------------------------
12: Parse and process command line arguments
15: Initialize plplot
20: Set up viewport and window
25: Draw the grid using plbox
28: Write the digits below the frame
38: Write the digits to the left of the frame
45: Display the symbols (plpoin expects that x and y are arrays so
45: pass pointers)
