SHOW KEYWORDS USED FOR SYMBOLS

Syntax:

SHOW KEYWORDS USED FOR SYMBOLS

SHOW KEYWORDS USED TO NAME SYMBOLS

Function:

FPT displays the names and attributes of all symbols which have the same names as Fortran keywords and intrinsic functions. The listing is organised in three sections: primary keywords, auxiliary keywords and intrinsics. A primary keyword is a keyword which may introduce a statement, such as INTEGER, IF or GOTO. An auxiliary keyword is a keyword which may occur only in specific contexts after one or more primary keywords, such as STATUS, PRECISION or CASE.

FPT always lists the symbols with the same names as keywords and intrinsic functions in the listing (.fpl) file. However, it is convenient to have the list available interactively, so that the information is visible when using the RENAME SYMBOL command.

Where to use this command:

Operating system command line

No


Configuration file, config.fsp

No


Specification (FSP) files, *.fsp

No


Interactively, to FPT> prompt:

Yes


Interactive command files

Yes


Embedded in the Fortran code

No


Example:

The list of keywords used for symbols is used as a guide for renaming the symbols to avoid name conflicts:

FPT> show keywords used for symbols

SELECT   SWITCH            Local                  LOGICAL *2
