Hi,   My output data (.DAT) is tab-delimited (used proc export) but because some observations have different lengths columns are not properly align. Every variable/column has same length $30.    Example of my output:             How I need them to be:                 I tried to use PUT statement but the output didn't change.   put  second_column @20 number_column @40;   -> this means that sas will start writing second_column starting with 20th character in the line and number_column will always start at 40th character. Did I get it wrong?   I'm new to sas and I try to understand it's ways. Any tip would help, thanks! ... View more
