------- Comment #4 from dominiq at lps dot ens dot fr 2010-09-09 23:20 ------- You can use the option -fno-range-check. However, the code itself and the sentence "since I want to protect this variable" in comment #3 let me suspect that you have not understood what PARAMETER is for: a variable with the PARAMETER "attribute" is an alias for its value and exists only during the compilation.
What you seem to want is the attribute PROTECTED, i.e. a variable that can be changed only in a specified place as in (F2003 standard draft): An example of the PROTECTED attribute: MODULE temperature REAL, PROTECTED :: temp_c, temp_f CONTAINS SUBROUTINE set_temperature_c(c) REAL, INTENT(IN) :: c temp_c = c temp_f = temp_c*(9.0/5.0) + 32 END SUBROUTINE END MODULE The PROTECTED attribute ensures that the variables temp_c and temp_f cannot be modi ed other than via the set_temperature_c procedure, thus keeping them consistent with each other. The PROTECTED attribute is a f2003 addition, implemented at least from gfortran 4.4. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45624
