 |
|
I have to compare two alphanumeric strings.
Presently 'ADD' and 'add' are treated differently as it is case sensitive.
I am aware of the below but I want to know if its possible to make this comparision not case sensitive.....any compile option? or alternate solution?
| Code: |
FUNCTION UPPER-CASE(input)
Option2: INSPECT string1 CONVERTING “abcdefghijklmnopqrstuvwxyz" TO "ABCDEFGHIJKLMNOPQRSTUVWXYZ”

You could convert everything to Upper case before trying to compare . . .

Thanks for the response Papadi.
Yes, thats my plan. I like to check on if there is a better option since there will be millions of records and converting both the fields for every record will raise the CPU time I believe. |

Vak255,
There are no compiler options to ignore the case. However given the 2 options you have, INSPECT solution is the optimal solution as it just involves 1 TR instruction where as UPPER-CASE function involves loading and calling the module IGZCUPL.
