I am trying to send IMS records from Mainframe to Linux and process using SAS. 

But when i read the file using SAS it shows  the minimum record length was 6 and maximum was 800 whereas in mainframe minimum record length was 24476 and maximum record length was 24476.

Can you please tell why SAS is interpreting differently on linux?

我的内联语句应该怎么写？

filename ims "/path/ims_fb.dat";

data test;
    infile ims recfm=f lrecl=24568;
    input record $char24568.;
run;

Check how the dataset was transferred from z/OS to Linux. If the original dataset has LRECL=24476 and RECFM=FB/VB, verify that the transfer preserved the record structure and that the file was transferred in binary mode. Also confirm whether EBCDIC-to-ASCII conversion was performed. On Linux, SAS may be treating newline characters or binary control bytes as record delimiters, which would explain why it reports record lengths between 6 and 800 instead of the expected fixed length of 24476. Knowing the original RECFM, FTP method, and SAS INFILE statement would help diagnose the issue.
