PLOTR is a simple, easy-to-use plotting program written in QuickBasic 3.0. The program is directive driven in nature, which means there are no complicated menu systems to navigate. The user simply instructs PLOTR what to do by using a command set. If the user forgets the legal commands, typing HELP will list the directives and a brief description of each directive's function. Currently, PLOTR operates on a system with an IBM CGA card or compatible. PLOTR is capable of plotting up to 5000 data points. It may also handle up to ten different sets of data (provided that the total points <5000). This means that the user could make one plot of 5000 points, two plots with 2500 points each, ten plots with 500 points, etc. The way PLOTR knows which data set you are referring to when issuing commands is by requiring the user to provide an identifier number (1-10) following the command. If this number is missing on the command line, PLOTR will prompt you for it. However, if only one data set has been entered, PLOTR will assume all commands refer to the first data set.
