Used like this : perl -MGVTax -e '' 48 GVs of which 8 (16.6667%) are defined or a partly exercised Tk demo: perl -MGVTax basic_demo ... 2807 GVs of which 110 (3.91877%) are defined I am not about to argue that 3000 SVs is going to amount to much, so if that is whole scope of the problem I will shut up again. > -- Nick Ing-Simmons <nik@tiuk.ti.com> Via, but not speaking for: Texas Instruments Ltd.Thread Previous
