ILERPG syntax parsing oddity

Ran across another thing that does not parse properly in RDi but does
compile. Frankly it's ugly and I did not think it WOULD compile, but it
did.

In a program I have included an include. There's a yellow triangle next to
it that says

Multiple markers at this line
- "." expected instead of this input
- unexpected token(s) ignored

I finally figured out that it meant not ON this line, but in the member
included by this line.

Went to the include and found this:

d functionName...
d pr extproc( 'functionName' )
d parm1 like(someStructure.
d Name )

I did not think the name in the like() keyword split on the period would
compile but it does. The parser hates it though. I don't much like looking
at it either...
