Get Month (Out: month) Level 1 |
|
|
|
|
|
|
|
|
DO
Read strMonth
Search(strMonthAry, strMonth, 12, index, found)
IF found
Set month = monthAry[index]
ELSE
Print error message
WHILE NOT found |

Now we can code the new function GetMonth. We must remember to initialize the arrays strMonthAry and monthAry. We also need to modify the Search function to make it work on string data. |
