I was looking for a program to slice pictures somehow to paste it on a globe(sphere). I found ip-slicer in this website. http://www.bruno.postle.net/2001/ip-slicer/ The problem I have is that I don't know where should I enter the command line. for example after running the program and entering this line "sphere-slicer.pl 16 1000 input.jpg" I get this this error

Number found where operator expected at - line 72, near "pl 16"
    (Do you need to predeclare pl?)
Number found where operator expected at - line 72, near "16 1000"
    (Missing operator before  1000?)
Bareword found where operator expected at - line 72, near "1000 input"
    (Missing operator before input?)

This program is written in perl language.
