Re^2: How can we read input argument file to a script from its main library?

Hi root, Thanks for your help. I have an idea of how handle command line arguments given to a script. Kindly go through the problem and background as below: Background : A script written to perform operation and all the depending subroutines for the script are in main library. Here no input arguments were accepted Problem : Now the input to file is an XML file. But I don't want to modify anything in local script. whereas when I call the script with xml file as a command line input, I should be able to read it directly in library. Is there a way to do this?

Have you looked at Getopt::Long and `@ARGV`? What problems do you have applying the ideas discussed there to your program? Maybe you also want to look at perlsub to find how to pass parameters to subroutines?	[reply] [d/l]

This is not the problem. In simple terms, can we use ARGV[0] of the local script directly in library?	[reply]

No, you should not use `@ARGV` anywhere outside the main program. Pass the parameter in your call to the library. See perlsyn.	[reply] [d/l]
