| 4 | + * process system functions and return a string result |
| 5 | + * |
| 6 | + * Notes: |
| 7 | + * 1) I return a string result because most of the functions cannot return any |
| 8 | + * normal type anyway (e.g. SYS_DATE, SYS_TIME, etc...), and the few that |
| 9 | + * might (SYS_UID or whatever) can just return it as a string - no problem. |
| 10 | + * This keeps the function flexible enough to be of good use. |
