Checks if a string contains only lowercase characters.
StringIsLower ( "string" )
| string | The string to check |
| Success: | 1. |
| Failure: | 0 if string contains non-lowercase characters. |
As in other StringIs...() the check is stop if a Chr(0) is encountered inside the string.
Internally the C function is used to speed up the processing.
Note that digits/punctuation/whitespace will cause StringIsLower() to return 0.
