File and Put to first blank line

Brian3 — Thu, 07 Nov 2019 23:22:05 GMT

Hi,

I have a simple problem (I hope). I am using file and put to write text to a different sas program. For example

data _null_;

file "filepath.sas";

put "x=1";

run;

Please can you tell me how I make it so the code writes the text to the first blank line of "filepath.sas". This is so when I run this again but with different text e.g. put "y=2", it doesn't overwrite the x=1, but adds to it underneath.

Thank you

You need to use the FILE statement option MOD.

It would be very hard to locate and overwrite the first blank line. But as @data_null__ says it is very easy to just append to a file by adding the MOD option to the FILE statement.
