SYMPTOMSUsing Microsoft FORTRAN versions 5.0 or 5.1 to compile a program that uses the LEN_TRIM intrinsic function on a character string that is defined as a PARAMETER may result in the following error:
fatal error F1001: Internal Compiler Error (compiler file '@(#)ctypes.c:1.12', line 467) STATUSMicrosoft has confirmed this to be a problem in FORTRAN versions 5.0 and 5.1 for MS-DOS and OS/2. This problem was corrected in FORTRAN PowerStation.
MORE INFORMATIONThe following program will generate the internal compiler error:
character*8 a parameter (a='abcdef ') print*,len_trim(a) endSince the length of a PARAMETER character is fixed, and therefore, the last nonblank character is known when the program is compiled, use of the LEN_TRIM function on PARAMETER character strings can be avoided by using this known constant value, or by using another PARAMETER to store this value. It is also possible to pass the PARAMETER as an argument to a function and to call the LEN_TRIM intrinsic function from within this user defined function without generating any errors. The following program illustrates this solution:
character*8 a parameter (a='abcdef ') integer*4 trim print*, trim(a) end integer*4 function trim(a) ! User-defined substitute ! for LEN_TRIM character*(*) a trim = len_trim(a) end |
