Hi Satya, Might I suggest to look up a bit into the function's source code? Because it's, well, pretty normal to call subs like that: ... some_func_call(-chan_range => "$beg-$end") ...
Of course, $beg and $end variables should be defined already (and contain numeric values, as I see). If not, warnings about attempting to interpolate undefined values will be shown. It's definitely not ok to use these without double quotation marks: $beg-$end is just $beg minus $end. -- iD 2011/11/29 Nemana, Satya <snem...@sonusnet.com> > Hi > > > > Sorry for the silly question, but thought someone might help here.(tried > googling but this may too silly a beginners question for anyone to have > answered previously) > > I need to pass argument to a function like this -chan_range => > "$chs-$che" > > Normally when this used which works -chan_range => "1-24" > > However, when I try to put variable values instead of a scalar string, I > get compilation errors (the errors are in different part of the code > which is completely clueless) > > What is the correct way to pass the values with variable names and - in > the string? > > I tried using \" and without the " also, but nothing helped. > > > > Thanks in anticipation, > > > > Regards, > > Satya > > > >
