SYMPTOMS
A program containing "!" (to denote an inline comment) directly following a string constant interprets the "!" as the letter "C" and appends a null character to the string.



STATUS
Microsoft has confirmed this to be a problem in Microsoft FORTRAN PowerStation 32 version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



MORE INFORMATION
String values in the C language are terminated with null characters. This type of string is specified in Microsoft FORTRAN by using a standard string constant followed by the character C. The code sample below shows how unwanted null characters are appended to string constants with "!" directly following.

Sample Code
OPEN (1, FILE='TEST') WRITE(1, '(A)') 'Normal string'     ! This is a normal FORTRAN c    string WRITE(1, '(A)') 'Normal C string'C  ! The C following the string c    constants indicates a C string WRITE(1, '(A)') 'Extra null char'! ! The "!" treats this c    string as a C string CLOSE (1) END
