_INFILE_ is a variable that allows you to access the input buffer when reading external data.

It is not an option.

Maxim 1: Read the documentation.

From INFILE Statement in DATA Step Statements:

INFILE_=variable

specifies a character variable that references the contents of the current input buffer for this INFILE statement. You can use the variable in the same way as any other variable, even as the target of an assignment. The variable is automatically retained and initialized to blanks. As with automatic variables, the _INFILE_= variable is not written to the data set.

Restriction	variable cannot be a previously defined variable. Ensure that the _INFILE_= specification is the first occurrence of this variable in the DATA step. Do not set or change the length of the _INFILE_= variable with the LENGTH statement or ATTRIB statement. However, you can attach a format to this variable with the ATTRIB statement or FORMAT statement.
Interaction	The maximum length of this character variable is the logical record length (LRECL= ) for the specified INFILE statement. However, SAS does not open the file to know the LRECL= until before the execution phase. Therefore, the designated size for this variable during the compilation phase is 32,767 bytes.
Tips	Modification of this variable directly modifies the INFILE statement's current input buffer. Any PUT _INFILE_ (when this INFILE is current) that follows the buffer modification reflects the modified buffer contents. The _INFILE_= variable accesses only the current input buffer of the specified INFILE statement even if you use the N= option to specify multiple buffers.
	To access the contents of the input buffer in another statement without using the _INFILE_= option, use the automatic variable _INFILE_.
	The _INFILE_ variable does not have a fixed width. When you assign a value to the _INFILE_ variable, the length of the variable changes to the length of the value that is assigned.
