INFILE

Valid:	in a DATA step
UNIX specifics:	file-specification and host-options

file-specification

can be any of the file specification forms discussed in Accessing an External File or Device .

host-options

are options specific to UNIX. They can be any of the following:

BLKSIZE=
BLK=

specifies the number of bytes that are physically read in one I/O operation. The default is 8K. The maximum is 1G-1.

LRECL=

specifies the logical record length. Its meaning depends on the record format in effect (RECFM). The default is 256. The maximum length is 1G.

• If RECFM=F, the value for the LRECL= option determines the number of bytes to be read as one record.

• If RECFM=N, the value for the LRECL= option must be at least 256.

• If RECFM=V, the value for the LRECL= option determines the maximum record length. Records that are longer than the specified length are truncated on input.

RECFM=

specifies the record format. Values for the RECFM= option are

D	default format (same as variable).
F	fixed format. That is, each record has the same length.
N	binary format. The file consists of a stream of bytes with no record boundaries.
P	print format.
V	variable format. Each record ends in a newline character.
