Hi! The following program
program a character(len=10) :: str str = '123' write( str, '(a,i1)' ) trim(str),4 print*,str end program a outputs [EMAIL PROTECTED] fem]$ gfortran -o a a.f90; ./a 4 all other compilers i've tried (sun f90, xlf, g95, ifort) seem to agree the output should be 1234 Regards, Juha -- Summary: write to internal unit from the string itself gives wrong result ?
