Argument Keywords in Intrinsic Procedures

For all intrinsic procedures, the arguments shown are the names you must use as keywords when using the keyword form for actual arguments. For example, a reference to function CMPLX(X, Y, KIND) can be written as follows:

Using positional arguments:

CMPLX(F, G, L)

Using argument keywords: 1

CMPLX(KIND=L, Y=G, X=F)

1 Note that argument keywords can be written in any order.

Some argument keywords are optional (denoted by square brackets). The following describes some of the most commonly used optional arguments:

BACK

Specifies that a string scan is to be in reverse order (right to left).

DIM

Specifies a selected dimension of an array argument.

KIND

Specifies the kind type parameter of the function result.

MASK

Specifies that a mask can be applied to the elements of the argument array to exclude the elements that are not to be involved in an operation.

Examples

The syntax for the DATE_AND_TIME intrinsic subroutine shows four optional positional arguments: DATE, TIME, ZONE, and VALUES. The following shows some valid ways to specify these arguments:

  ! Keyword example
  CALL DATE_AND_TIME (ZONE=Z)

  ! Positional example
  CALL DATE_AND_TIME (DATE, TIME, ZONE)
