Is allocate a function or subroutine?

[fortran4r]

This question came to me when I was driving today.

[milancurcic]

It’s a statement.

Rules of thumb I use to tell them apart:

• Function calls appear in expressions.
• Subroutine calls begin with call.
• Statements stand on their own.

I mistakenly write call allocate(...) more often than I care to admit
