------- Comment #2 from burnus at gcc dot gnu dot org 2008-11-24 17:07 ------- Regarding <TAB>: Standard Fortran does not allow tabs, as extension gfortran does. Thus you do not need to change the code (though it does not harm to be standard compliant - that is what the warning tells you). But one needs to be careful: By default, every character after column 72 is ignored; I forgot how this interplays with tabs (i.e. whether they count as 1 or as 6 spaces).
The line "read(*,*)x,y" looks harmless and of cause works here with a simple test program; the line should work since early gfortran 4.0.0. Can you attach a minimal program which fails? And include the exact command you entered and the exact gfortran version ("gcc version" and the "Target:" line shown by "gfortran -v"). Additionally, you could try a newer version, cf. http://gcc.gnu.org/wiki/GFortranBinaries, though I would expect that this does not help as the problem is probably elsewhere. (I'd expect that it is a bug in your program.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38249
