GE 90-30/20/Micro manual Const -+FNC

4

Example:

In the following example, when called for by previous logic, a parameter block for the time-of-day clock is built to first request the current date and time, and then set the clock to 12 noon using the BCD format. The parameter block is located at global data location %R0300. Array NOON has been set up elsewhere in the program to contain the values 12, 0, and 0. (Array NOON must also contain the data at %R0300.) The BCD format requires six contiguous memory locations for the parameter block.
