You already got suggestions on how to fix these errors: `Variable "$CONFIG" is not imported at ./Chapter9_Exer3 line 15. Variable "$OUTPUT" is not imported at ./Chapter9_Exer3 line 20. Global symbol "$CONFIG" requires explicit package name at ./Chapter9_E +xer3 line 15. Global symbol "$OUTPUT" requires explicit package name at ./Chapter9_E +xer3 line 20.` [download] You open the filehandles `CONFIG` and `OUTPUT`, and then try to use the variables `$CONFIG` and `$OUTPUT`, these are two different things. You need to either change your open calls to use lexical variables, like I showed here, or remove the `$` sigil, as pointed out by Your Mother and kcott. `syntax error at ./Chapter9_Exer3 line 8, near "'three_Freds.out':" Can't use global $0 in "my" at ./Chapter9_Exer3 line 12, near "Usage: +$0"` [download] The first error was pointed out by poj: You have a typo in that line. The second error is just being caused by the parser getting confused after seeing the first error.	[reply] [d/l] [select]
