By script, I'm assuming you are talking about a SAS program.
Anyway, the answer to your question, whatever your script maybe is no.
You'll have to code that yourself.
A macro with a more or less intelligent behavior could split the content of your files for the 80 char line limit, which exists on MVS.
The easiest way to do this would be to parse each line look for the nearest blank char ' ' under the 80 char limit, still this could produce some weird splits (say at the middle of constant value or expression).
Another way would be to parse to the nearest blank ' ', or ',' or ';', like the following code:
length INLINE $1024;
* under limit no line cut;
if length(_INFILE_) le &LIMIT then put _INFILE_;
else do; * try to cut the line;
do while (length(INLINE) gt &LIMIT);
do while (DLM not in (' ',',',';')); * line delimiters;
if I = 0 then do;
put 'no valid delimiters where found, could not process line:';
* cut the line;
* check if the remaining is under limit;
if length(INLINE) le &LIMIT then do;
