| /* DGDATE |
| Two functions do encode/decode dates in DG system format. |
| |
| Usage: |
| long value,year,month,day; |
| |
| value=dgdate(month,day,year); |
| undgdate(value,&month,&day,&year); [GRR: not used in UnZip: removed] |
| |
| Notes: |
| |
| 1. DG date functions only work on dates within the range |
| Jan 1, 1968 through Dec 31, 2099. I have tested these |
| functions through the same range with exact agreement. |
| For dates outside of that range, the DG system calls |
| may return different values than these functions. |
| |
| 2. dgundate() accepts values between 0 and 48213 inclusive. |
| These correspond to 12/31/1967 and 12/31/2099. |
| |
| 3. Both functions assume the data is in the native OS byte |
| order. So if you're reading or writing these fields from |
| a file that has been passed between AOS/VS and PC-DOS you |
| will need to swap byte order. |
| |
| 4. With reference to byte order, the entire range of values |
| supported by these functions will fit into an unsigned |
| short int. In most cases the input or output will be |
| in that variable type. You are better off casting the |
| value to/from unsigned short so you only need to concern |
| yourself with swapping two bytes instead of four. |
