specifies a number
to indicate when to stop processing. Using one of the letter notations
results in multiplying the integer by a specific value. That is, specifying
K (kilo) multiplies the integer by 1,024, M (mega) multiplies by 1,048,576,
G (giga) multiplies by 1,073,741,824, or T (tera) multiplies by 1,099,511,627,776.
You can specify a decimal value for n when
it is used to specify a K, M, G, or T value. For example, a value
of 20 specifies 20 observations or records,
a value of .782k specifies 801 observations
or records, and a value of 3m specifies 3,145,728
observations or records.
- hexX
-
specifies a number
as a hexadecimal value to indicate when to stop processing. You must
specify the value beginning with a number (0–9), followed by
hexadecimal characters (0–9, A–F), and then followed
by an X. For example, the hexadecimal value F8 must be specified as 0F8x in
order to specify the decimal equivalent of 248. For example, the value 2dx specifies
the decimal equivalent of 45.
- MIN
-
sets the number to
0 to indicate when to stop processing.
If OBS=0 and the NOREPLACE
option is in effect, SAS might still be able to take certain actions.

OBS= System Option in SAS System Options: Reference.
- MAX
-
sets the number 9,223,372,036,854,775,807
to indicate when to stop processing.
