MIN Function
The MIN function returns the content of the parameter-1 that contains the
minimum value. The function type depends on the parameter type, as
follows:
Parameter Type Function Type
Alphabetic Alphanumeric
Alphanumeric Alphanumeric
All parameters integer Integer
Numeric (some parameters may be Numeric
integer)
Syntax
FUNCTION MIN ({parameter-1}...)
Parameters
parameter-1 If more than one parameter-1 is specified, all
parameters must be of the same class.
Return Value
The returned value is the content of the parameter-1 having the least
value. The comparisons used to determine the least value are made
according to the rules for simple conditions. See the section "Simple
Conditions" in Chapter 8 for additional information.
If more than one parameter-1 has the same least value, the content of the
parameter-1 returned is the leftmost parameter-1 having that value.
If the type of the function is alphanumeric, the size of the returned
value is the same as the size of the selected parameter-1.
Example
77 A PIC X VALUE "A".
77 B PIC X VALUE "Z".
77 C PIC X VALUE "m".
77 D PIC X VALUE "9".
77 I PIC 9 VALUE 8.
77 J PIC 9 VALUE 3.
77 K PIC 9 VALUE 6.
77 L PIC 9 VALUE 1.
77 MIN-VALUE PIC 9 VALUE ZERO.
01 TAB.
05 ELEMENT PIC S999V99
OCCURS 4 TIMES VALUE ZERO.
:
DISPLAY FUNCTION MIN (A, B, C, D).
COMPUTE MIN-VALUE = FUNCTION MIN (I, J, K, L).
DISPLAY MIN-VALUE.
MOVE 1.25 TO ELEMENT (1).
MOVE 3.50 TO ELEMENT (2).
MOVE 8.75 TO ELEMENT (3).
MOVE 0.25 TO ELEMENT (4).
COMPUTE MIN-VALUE = FUNCTION MIN ( ELEMENT (ALL) ).
DISPLAY MIN-VALUE.
