Get a value from a table.
First, the given key is looked up, if this fails, the value at the given position is looked up, and if this also fails, the default value is returned. Positional addressing is only valid, as long, as no value was provided by an explicit key in the list before the entry in question.
Retrieve a single precision real value from a table.
Type | Intent | Optional | Attributes | Name | ||
---|---|---|---|---|---|---|
real(kind=single_k), | intent(out) | :: | val | Value of the table entry if it exists. |
