| 3 | 15 | simandl | (W uninitialized) An undefined value was used as if it were already |
| 4 | | | defined. It was interpreted as a "" or a 0, but maybe it was a mistake. |
| 5 | | | To suppress this warning assign a defined value to your variables. |
| 6 | | | |
| 7 | 27 | simandl | To help you figure out what was undefined, perl will try to tell you |
| 8 | | | the name of the variable (if any) that was undefined. In some cases |
| 9 | | | it cannot do this, so it also tells you what operation you used the |
| 10 | | | undefined value in. Note, however, that perl optimizes your program |
| 11 | | | anid the operation displayed in the warning may not necessarily appear |
| 12 | | | literally in your program. For example, "that $foo" is usually |
| 13 | | | optimized into "that " . $foo, and the warning will refer to the |
| 14 | | | concatenation (.) operator, even though there is no . in |
| 15 | | | your program. |
