in reply to Re^3: Dynamic option
in thread Dynamic option

To explain again ,the ones in "[]" are optional sub-options(they may or may not present always) to the values of "input"option, data,modem,apps are values to option "input",they can also change. 
EXAMPLE:-
findfiles -input [-nd -na ] data [-nc -nd] modem apps -des "finding fi
+les" -r 1000

Basically ,pseudco code of what I want to achieve is below.Really appr
+eciate if someone can give me the perlversion of the code.
for each "input option value"
{

call function A if not exits nd

call function B if not exits na

call function C if not exists nc
}

    So? If the value is optional, tell Getopt::Long it's optional. 

    --input
--input=nd
--input=na
--input=nd,na

    As the author of Getopt::Long always says, options are optional, or they wouldn't be options. So the "they may or may not be present" isn't anything special. In fact, it's the bread and butter of Getopt::Long - it only deals with things that may or may not be present.

    If you make the call syntax like: 

    findfiles --input data modem apps --nd --na --nc --des "..." -r 1000

    Something like: 
    GetOptions 'input=s{0,}'  =>  \my @input,
           'na'           =>  \my $na,
           'nd'           =>  \my $nd,
           'nc'           =>  \my $nc,
           'des=s'        =>  \my $des,
           'r=i'          =>  \my $r;

    Should do the trick.

      That's not what the OP wants. He wants to be able to specify 'nd' for -input (or not), and again for data (or not).

      Your solution only permits specifying it once (although it could be changed to counted), and it's not associated with "input" or "data".
