Hi Chris, I wonder if you have chance to help me with this problem? thanks.

I got hundreds of file need to unzip. The main code for unzip in sas works for me, however, there are two major problems;
1, input: right now, 'input;' can function, but does not work properly, only work when you specify the variables and length and format, this causes lots of trouble, as we have to re-define all the variables and format. Especially when dealing with different table, it's a disaster.

I hope to have a simple command to universally treat input;

2, Any way to unzip a batch of files? Got hundreds, batch by batch and I don't want to do it one by one.
