What is the difference between .hpgl and .pam?

Description: The HPGL file format, standing for HP Graphics Language Plotter File, is a specialized file type developed by Hewlett-Packard. It is primarily used for controlling plotter devices, which are printers that draw images with lines instead of dots, making them ideal for engineering and architectural drawings. HPGL files contain a series of two-letter instruction codes followed by parameters that direct the plotter's drawing operations, such as moving to a point, drawing a line, or selecting a pen.; The PAM image format is a lowest common denominator 2 dimensional map format. It is designed to be used for any of myriad kinds of graphics, but can theoretically be used for any kind of data that is arranged as a two dimensional rectangular array.
