When reading in external raw data files,you can, for the most part, rely on default values for describing architectural features of the files.You can override defaults when necessary,to describe such features as the record format,block size,or logical record length of the file.These features are described by the INFILE statement options RECFM=, BLKSIZE=,and LRECL= respectively.
We only concern ourselves here with the last one,LRECL=.(By the way, this option is named after that famous Spanish bullfighter,"El Rec-el.")You use this option to indicate the maximum record length of the input file and only need it when the record length exceeds your system dependent default.Suppose you have a file,LONGFILE,with 256-byte records and a system default logical record length of 80.You can account for the long record length by coding the INFILE statement as follows:INFILE 'LONGFILE' LRECL=256;
You can also use the LRECL= option when you want to read only part of very long records. You may code an LRECL= value larger or smaller than the actual record length in your input file and it will work just fine.
Hint: Use the DOLLAR7, informal to read PRICE.
They are recorded as follows:
Write a program that uses absolute and relative pointers to read the sample data below.Create a SAS data set called PRESSURE.Hint: Read all the SBP's first, then go back and read the DBF's.
If column 12 is a 2, the record layout is:
Write a SAS program to create a SAS data set called HTWT. Use column input
and do not include the data instream.
