List of Variable Names and Lengths

This option is available for controlling the size of the variables in the output data set.

Note: This option becomes available only when the List of Variable Names and Types option is specified.

List all variable names followed by their desired length. If a variable type is character, include a $ between the variable name and the desired length. Separate names by an empty space or use ranges of variables with no spaces before or after a hyphen. For example, specify

ID $5 Sex $1 Age 3 SNP1-SNP100000 $2

to set lengths of 5, 1, 3, and 2 for variables ID, Sex, Age, and all SNP1-SNP100000, respectively. Note that no parentheses are required as in the previous parameter (List of Variable Names and Types).

Lengths for numeric values can range from 3 to 8.

Leave this field empty for the system to automatically set the variable length as determined by the Number of Rows to Scan.

Refer to Base SAS documentation on the LENGTH statement for additional details.

To Specify the List of Variable Names and Lengths:
