MINIMUM Function

Returns the minimum numeric element in a dynamic array.

Syntax

MINIMUM(dynamicArray)

Syntax Elements

dynamicArray is the name of a dynamic array.

Comments

Array elements can contain non-numeric values, which are ignored. The functions returns a null if all array elements are non-numeric and non-null.

Null elements evaluate to zero.

Array delimiters do not need to be the same character, but they must be either an attribute mark (AM), a value mark (VM) or a subvalue mark (SVM).

Examples

EQU AM TO CHAR(254)
ZIP = "92626":AM:"92714":AM:"92720"
X = MINIMUM(ZIP)

Assigns the value 92626 to variable X.

EQU AM TO CHAR(254)
EQU VM TO CHAR(253)
EQU SVM TO CHAR(252)
ARR = "4":AM:"3":VM:"67":VM:"9":SVM:"39":SVM:"11"
Y = MINIMUM(ARR)
PRINT Y

Prints the value 3, the minimum numeric value in dynamic array ARR.

W = "RECORD":AM:"":AM:"334"
X = MINIMUM(W)
PRINT X

Prints a zero, because null elements evaluate to zero.

A = "BOSTON":VM:"MA":AM:"SACRAMENTO":VM:"CA"
B = MINIMUM(A)

B is assigned a null value, because there are no numeric values or nulls in the array.
