Reading Raw Data

Sources of Raw Data

The following example uses the INPUT statement to read in instream data:

data weight;
   input PatientID $ Week1 Week8 Week16;
   loss=Week1-Week16;
   datalines;
2477 195 177 163
2431 220 213 198
2456 173 166 155
2412 135 125 116
;

Note: A semicolon appearing alone on the line immediately following the last data line is the convention that is used in this example. However, a PROC statement, DATA statement, or global statement ending in a semicolon on the line immediately following the last data line also submits the previous DATA step. [cautionend]

Instream Data Containing Semicolons

The following example reads in instream data containing semicolons:

data weight;
   input PatientID $ Week1 Week8 Week16;
   loss=Week1-Week16;
   datalines4;
24;77 195 177 163
24;31 220 213 198
24;56 173 166 155
24;12 135 125 116
;;;;

External Files

The following example shows how to read in raw data from an external file using the INFILE and INPUT statements:

data weight;
   infile file-specification or path-name;
   input PatientID $ Week1 Week8 Week16;
   loss=Week1-Week16;
run;

Note: See the SAS documentation for your operating environment for information on how to specify a file with the INFILE statement. [cautionend]
