S2V= System Option

Specifies the starting position to begin reading a file that is specified in a %INCLUDE statement, an autoexec file, or an autocall macro file with a variable length record format.

Syntax

S2V=S2 | S | n | nK | nM | nG | nT | MIN | MAX | hexX

Syntax Description

S2: specifies to use the current value of the S2= system option to compute the starting position of the variable-sized record to read from a %INCLUDE statement, an autoexec file, or an autocall macro file. This is the default.
S: specifies to use the current value of the S= system option to compute the starting position of the variable-sized record to read from a %INCLUDE statement, an autoexec file, or an autocall macro file.
n | nK | nM | nG | nT: specifies the starting position of the variable-length record to read that comes from a %INCLUDE statement, an autoexec file, or an autocall macro file, in terms of 1 (bytes); 1,024 (kilobytes); 1,048,576 (megabytes); 1,073,741,824 (gigabytes); or 1,099,511,627,776 (terabytes). For example, a value of 8 specifies 8 bytes, and a value of 3m specifies 3,145,728 bytes.
MIN: sets the starting position of the variable-length record to read that comes from a %INCLUDE statement, an autoexec file, or an autocall macro, to 0.
MAX: sets the starting position of the variable-length record to read that comes from a %INCLUDE statement, an autoexec file, or an autocall macro, to 2,147,483,647.
hexX: specifies the starting position of the variable-length record to read that comes from a %INCLUDE statement, an autoexec file, or an autocall macro, as a hexadecimal number. You must specify the value beginning with a number (0-9), followed by an X.

Details

Both the S2V= system option and the S2= system option specify the starting position for reading variable-sized record input from a %INCLUDE statement, an autoexec file, or an autocall macro file. When values for both options are specified, the value of the S2V= system option takes precedence over the value specified for the S2= system option.

Operating Environment Information: The syntax shown here applies to the OPTIONS statement. On the command line or in a configuration file, the syntax is specific to your operating environments. For details, see the SAS documentation for your operating environment. [cautionend]

Comparisons

The S2= system option specifies the starting position for reading both fixed-length and variable-length record formats for input from a %INCLUDE statement, an autoexec file, or an autocall macro file. The S2V= system option specifies the starting position for reading only variable-length record formats for input from a %INCLUDE statement, an autoexec file, or an autocall macro file.
