Certain systems ignored trailing characters.  This would not be under 
the control of g77.  Supposing that your system has a tool such as nm, 
use it to check that all the characters appear in the compiled object. 
There's little reason to use g77 now, unless for historic reasons.  It 
hasn't been maintained for several years.  Several current f95 compilers 
aim to sup****t practically all source code which was valid for g77.
