Language Reference

MAX(A1, A2, A3, ...)

Maximum value.

• A3, ... are optional arguments. Any array that is itself an optional dummy argument must not be passed as an optional argument to this function unless it is present in the calling procedure.
• All the arguments must have the same type, either integer or real, and they all must have the same kind type parameter.

Class

Elemental function

Result Type and Attributes

Same as the arguments. (Some specific functions return results of a particular type.)

Result Value

The value of the result is that of the largest argument.

Examples

MAX (-9.0, 7.0, 2.0) has the value 7.0.

If you evaluate MAX (10, 3, A), where A is an optional array argument in the calling procedure, PRESENT(A) must be true in the calling procedure.

Notes:

1. IBM Extension: the ability to specify a nondefault integer argument.

2. IBM Extension: the ability to specify a nondefault real argument.
