SEQ=n| MIN | MAX | hexX

Syntax Description

n

specifies the length in terms of bytes.

MIN

sets the minimum length to 1.

MAX

sets the maximum length to 8.

Tip:	When SEQ=8, all eight characters in the sequence field are assumed to be numeric.

hexX

specifies the length as a hexadecimal. You must specify the value beginning with a number (0-9), followed by an X.

Details

Unless the S= or S2= system option specifies otherwise, SAS assumes an eight-character sequence field. However, some editors place some alphabetic information (for example, the filename) in the first several characters. The SEQ= value specifies the number of digits that are right-justified in the eight-character field. For example, if you specify SEQ=5 for the sequence field AAA00010, SAS looks at only the last five characters of the eight-character sequence field and, if the characters are numeric, treats the entire eight-character field as a sequence field.
