* The purpose of JJB is to help you to write programs as quickly *
* as possible. JJB handles things for you and provides you with *
* an environment which allows you to concentrate on the functions *
* of your program. *
* *
* This example shows you how to use the following functions: *
* *
* jjb_initalize() initalizes JJB. *
* jjb_setup() sets up the JJB option arrays. *
* jjb_start() begins executing the default option. *
* *
* group(group description) start setting up a group of options & *
* assign a description to the group. *
* *
* option(option description) sets up an option. *
* *
* funct(function name) assigned a function to the option. *
* default_opt() assigns default to an option *
* help(functionname) assigns a function to F1 help. *
* *
* *
* If you are looking at this file from DOS, you need to first read *
* JJBREAD.ME file and follow the instructions. *
* *
* You may now press 'F5' to compile and begin executing. *
