You've selected a style of INPUT which is overly complex for the data that you are reading. Why not just use a straightforward statement?

input id 1-4 name $ 6-25 age 26-27 sex $ 30-35 sal 37-41;

That is because you used the & modifier. That instructs SAS to stop when it sees two or more spaces.

So on the first line

  172 infile datalines ;
  173 input id 5. name&$20. age 3. sex$7. sal 5.;
NOTE: Invalid data for sal in line 175 33-37.
RULE: ----+----1----+----2----+----3----+----4----+----5----+----6
  175 1002 sarvesh ranjani      30 male 32000
id=1002 name=sarvesh ranjani age=. sex=30 mal sal=.

It starts to read the last three fields at 23 instead of column 26.

So it reads columns 23-25 into AGE and since they are blank it sets AGE to missing.

It then reads columns 26-32 into SEX so SEX is set to '30 mal' , since the $7. informat will left align the value.

When it tries to read SAL it sees 'e 320' which is not a valid number.
