There is pretty much only one place to look at for ever requiring 
blanks anywhere. Remember that this is an issue specific to free source 
form. Blanks make no difference in fixed source form (except in 
character contexts). So it is in the section on free source form (3.3.1 
of f95). The 2nd para of that section is about places where blanks are 
disallowed; the 3rd para is about places where blanks are required.  
Namely...

"A blank shall be used to separate names, constants, or labels from 
adjacent keywords, names, constants, or labels."

The function name is a name. REAL and FUNCTION are keywords.

(Oh, and the next para is about adjacent keywords, which have a bunch 
of special cases. It covers why you need the space between REAL and 
FUNCTION.)
