Description Kris CLA 2010-12-04 15:23:13 EST 
Build Identifier: 20100917-0705

forall statements like:

forall (i=1:10, j=1:10) A(i,j) = 2.0

are considered syntax errors.  If I re-write them as constructs like so:

forall (i=1:10, j=1:10) 
  A(i,j) = 2.0
end forall

then they are not considered errors.  I am importing some code that is valid fortran and compiles with several different compilers. 



Reproducible: Always

Steps to Reproduce:
1. install eclipse
2. open source file with forall statement
3. syntax error
4. close eclipse and continue to work in emacs

This has been reported before (see bug 308196 and also bug 314043 ), and should have been fixed in 6.0 RC2, according to Jeffrey Overbey.

I'm currently running 7.0.0.201011121412 and don't get this error anymore.
Comment 2 Jeffrey Overbey CLA 2011-03-17 12:25:41 EDT 
This appears to be a different problem -- the parser is rejecting forall statements with more than one triplet-spec
Comment 3 Jeffrey Overbey CLA 2011-03-17 12:29:49 EDT 
This will be fixed in the next 7.0 build.  Thanks again for the bug report!
