The following program has a coding mistake - internal i/o overflow in
the write statement.  This program will generate a runtime error message
when compiled with the HP-UX and AIX fortran compilers.  When compiled
using g77, program execution will hang at the write statement. 
Compiling with the -fbounds-check has no effect.  If the format is
changed to "(2a)", then the program will run without any messages.  But
it ought to generate a runtime error about the overflow, at least when
compiled with -fbounds-check.
