OPTIONS

subprogram analysis:

-      Analyze all columns of the source input records.
-      Accept a maximum number of continuation lines.
-      Present a warning for all variables that are not explicitly declared.
-      Process conditional compilation (debug) lines.
-      Flag all referenced subprograms which have not been declared
       external.
-      Flag all language extensions which are not in the Fortran 90
       standard.
-      Source input is in free-format.
-      Integers occupy 2 bytes storage by default. The length of logicals
       depends on the compiler emulation chosen.
-      Integers and logicals occupy 4 bytes storage by default.
-      Integers and logicals occupy 8 bytes storage by default.
-      Flag all Fortran 90 obsolescent syntax features.
-      Relax type checking between integers, logicals and Holleriths.
-      Apply rigorous syntax analysis and verify portability.
-      Check the syntax to conform to the ANSI Fortran 77 standard.
-      Truncate names to 6 significant characters.


global analysis:

-      Signal unreferenced subprograms, unreferenced common blocks,
       unreferenced and undefined common-block elements.
-      Verify the consistency of the program.
-      Analyze the reference structure.


output:

-      Maximum number of lines n on an output page, n > 10.
-      Generate listings and cross-references of subprograms.
-      Generate cross-reference of elements of specified common
       block(s).
-      List statements of include files.
-      Include unreferenced constants, declared in include files, and
       unreferenced common-block elements in the cross-references.
-      Present the program cross-references.
-      Present the reference structure for the roots specified.
-      List source lines.


libraries:

-      Create new library and insert analyzed subprograms in it.
-      Include all subprograms from this library file in the analysis.
-      Include specified subprograms in the analysis.
-      Update library with the analyzed subprograms.


miscellaneous:

-      Exit if errors during command input.
-      Present help information on the screen.
-      Show informative messages.
-      Specify include paths.
-      Log and show internal table usage.
-      Show warnings.
