Since your lines are 80 characters or less when you try to read 100 characters from them SAS will go to the next line to find enough characters.

Either add an INFILE statement so that you can specify the TRUNCOVER option to prevent SAS from going to a new line,

 

data aa00;
  infile cards truncover ;
  input name $100.;
cards;

or since you seem to want to read the whole line you could just use the _INFILE_ buffer.

data aa00;
  length name $100 ;
  input;
  name = _infile_;
cards;

or don't use such a large informat. Note in-line data (CARDS/DATALINES) will have a LRECL that is a multiple of 80. 

data aa00;
  input name $80. ;
cards;

Read the log. 

 

NOTE: SAS went to a new line when INPUT statement reached past the end of a line.
NOTE: The data set WORK.AA00 has 10 observations and 1 variables.
NOTE: DATA statement used (Total process time):
real time 0.00 seconds
cpu time 0.01 seconds
 
When you specify $100 inline (on the INPUT statement) like that SAS is trying to find 100 characters. If you're trying to specify the variable length, try using a LENGTH or INFORMAT instead.
 
data aa00;
informat name $100.;
input name;

Thank you all so much !

 

I also like the funny cartoon you shared with us.

In my opinion you should ALWAYS set an explicit length for your character variables. If you don't you could end up with the same variable on different files having different lengths which could lead to problems if you try to to append or merge them.
