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. |
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)
