FIle path in Screen Programming

Former Member — Mon, 15 Sep 2008 13:08:17 GMT

Hi I am new to screen programming.

My program would pick a file from desktop and process it.

I am a bit confused how would I give the file path. Should it be a input/output field??

I want something like,

PARAMETERS: filename TYPE text255 OBLIGATORY.

ANy suggestions.

Ster.
