Two ways of exploring this:

Test yourself, be using different lengths in your program.

Hi @LineMoon

My 2 cents here:

If i understood correclty you want to ask, if there will be a difference in the size of the file created, if you use LRECL and if you don't.

Please note that, if you don't use LRECL= in the file ouput statement, then sas by default uses the LRECL=32767 and creates the file.

if your data has record length less than 1000 and you use lrecl=1000, then there won't be any difference in size, cause its the logical length and not physical length , which denotes the maximum bytes it can store in a row.

Thanks,
