CHANGE COMMENT DELIMITER

Syntax:

CHANGE COMMENT DELIMITER TO <string>
COMMENT DELIMITERS AS WRITTEN

Function:

Fortran 77 line comments may begin with the characters C, c, * and ! in column one. The command COMMENT DELIMITERS AS WRITTEN instructs fpt to transcribe line comments with the original delimiter character. The command CHANGE COMMENT DELIMITER TO <string> instructs fpt to change the line comment delimiter systematically to the specified character. The character is written as a quoted string in the fpt command.

The line comment delimiters * and ! are not accepted by all Fortran compilers. In particular, the Salford FTN77 compiler does not accept the character! in column one (though it does allow trailing comments delimited by ! characters). By default, fpt inserts header comments and diagnostic comments into the code which begin with ! characters. The command CHANGE COMMENT DELIMITER TO "C" (or to "*") should always be used when preparing programs for the Salford FTN77 compiler.

Where to Use this Command

Default

COMMENT DELIMITERS AS WRITTEN

(Note that defaults may be changed in the configuration file).

Examples:

The original code:

* Rotate to new coordinates CALL COORD3(C(1),C(2),C(3),DX,DY,DZ,THETA,PHI,0)

In which fpt is to report a diagnostic, is re-written, with the command

% CHANGE COMMENT DELIMITER TO "C"

C Rotate to new coordinates CALL COORD3(C(1),C(2),C(3),DX,DY,DZ,THETA,PHI,0.0D0) C-------------------------------------------------------^------- C!! fpt - 1873 Actual argument changed to match formal argument C---------------------------------------------------------------

Note that the leading exclamation marks in the diagnostic message have been changed to C comment delimiters.
