How should I use parameter strings on my program?

Im coding a console program that will have a lot of parameter strings.
myapp -param1 param2 -param3 param4 ...etc


How could i do it without "else if". I dont want to repeat that for 400 parameters.
I've been thinking on using switch case and converting the param string to a number hash.

Is there any easier way to do it?

This depends on the language, but you could do a key-value-pair with the parameter and a function for processing that thing.

Then it'll just be
>look up the function for that argument
>execute the function
