toUpperCase
char toUpperCase(
string s,
int index)
s | The name of an event field containing a string. |
index | The index of the character within the string field that is to be returned. This index is zero-based, so the first character has an index of 0. |
Returns a copy of the string from the event field with the name specified by s, but with all lowercase characters converted to uppercase. Any non-alphabetic or uppercase characters in s are returned unaltered.
Note:
This function supports locale sensitivity to the extent possible on your particular platform.
