Sorry for asking a very basic question. I am trying to do the following with a test.DAT file. The file contains data in various columns that I want to replace to a constant or a random value. However in some cases there might be no data for that particular field length.
Start Colum = 161 End Column = 190 , If there is text set to value MYTEXT
Start Column = 221 End Column = 230 , If there is text set to value 01/01/1980
Start Column = 231 End Column = 245 , If there is text set to value random 15 numbers
And leave everything else unchanged.
Thanks you so much in advance.
