Hallo,
"convert_data" kann ich problemlos aufrufen, allerdings findet das Programm "&main::read_input" nicht...
perldoc -f use:
imports some semantics into the current package from the named module, generally by aliasing certain subroutine or variable names into your package. It is exactly equivalent to
BEGIN { require Module; import Module LIST; }
except that Module must be a bareword.....
Also der Rest sollte klar sein, oder?
Grüße
Klaus
