[Greg Field]

Released version :
------------------

    23.07.01


New features.
-------------

    New usability features :

        MAC EXEC for managment and execution of macros.

        HIS EXEC for easy use of history in screen mode.

        "Exec" as a sub-command has come to mean a higly useable _screen_mode_ menu.

    CC compiler modes.
        6 addional modes and menu for tuning your compile.


Discussion
----------

    This release adds some important usability features.

    MAC EXEC is a screen mode menu for executing macros easilly.
    If MAXEXEC mode is set to EXPERT, then MAC EXEC becomes a file manager
    like tool for finding, viewing, moving, printing and executing macros.

    HIS EXEC is a screen mode menu for easily finding and re-executing a
    command from history.

    There is a new pull down menu for compiler flags.
    6 compiler modes added to guide compilation.

    There are several bug fixes.


Program options
---------------

    -path path:directory:list

        Sets your macro path (like the PATH command) at program invocation.

Commands
--------

    New
    ---

    EXPORT shell_var = "value"

        Sets a shell variable.
        'shell_var' does not need to be an Open/ed variable but it can be.

    Changes
    -------

    MAC EXEC and HIS EXEC.

    '*' is deprecated in PATH and LEARN PATH. Use '.' instead.

    CLOSE can now be used to close an open operating system table.
    Supported tables are 'passwd' and 'group'.
    Parenthesis are not needed at the command line.
    Use this when a macro using SETPWENT() or SETGRENT() aborts early
        leaving the table(s) open.

Abbreviations
-------------

    No change.


Modes
-----

    New compiler modes.

    Controls Clang compiler options.

    CCERLIMit

        This mode sets the error limit.

    CCLANGflav

        This mode sets the language flavour for the compiler.

    CCOPTimise

        This mode sets the compiler optimisation.

    CCSYNTaxonly

        This mode cause a syntax only compile.

    CCUSERargs

        This mode adds additional user specified flags to the compile.

    CCWARNALL

        This mode sets on all warnings.

    CCWUNDEFmac

        This mode causes a warning for all undefined #define macros.

    CCWUNUSednames

        This mode causes a warning for any variable that is defined but unused.


    HISTORY mode has new sub opti0ons :

        ADDHIS removed.
        NO/REPEAT added.


    SHELLESC

       Adds shell escapes to system command lines.
       Currently SHELLESC adds escapes to '(' and ')'.

Functions
---------

    New
    ---

    let int# = SETENV ( 'NAME' , %value% )

        Sets a shell environment variable. Does not have to be an Open/ed variable but can be.

    let int# = LEAPYEAR  ( 2023 )

        Retuns true or false if the year is a leap year.

    let int# = strall ( "string" , 'char' )

        Return true if the string is all 'char'.


    Changes
    -------

    Warning : these will effect existing macros.

    str# = AFTER / AFTERFIRST / AFTERLAST
    str# = BEFORE / BEFOREFIRST / BEFORELAST
    str# = PREFIX / SUFFIX.

    These functions have had their two arguments reversed.
    It is now :

        str# = AFTER ( "look_for" , "in_this" )

    The first argument is what to look for and the second is the string to search.
    This makes the defaults more useable.

    Default "in_this" is %text% and PREFIX/SUFFIX is %file.name%.

    SETPWENT() and SETGRENT() _MUST_ be called before calling
    GETPWENT() and GETGRENT(). Open/ed now keeps track of open tables.

    The xxPWENT() and xxGRENT() functions now return -1 or 0 rather than 0 and 1.
    All functions have a returns code consistent with the operating system.

    The MENU() function now has an optional separator and title.

Variables
---------

    New :

        %private%.macros%  and  %public.macros% are settable with LET ...

        %tag.count% added as a synonym for %total.tagged%.

    Removed variables :

        None.

    Changed variables :

        None.

---------

    New constants :

        None.

    Changes :

        STR_MAX is now STRING_MAX.

    22-018 WHICH double reports on "." and same directory in PATH.
    22-015 Shared mem still splits to different segments after crash.
    23-007 Click on ALERT message sometimes does not register in alarm system.
    23-029 MODE() help needs more constants for modes ...
            LR,SR,TAB,WAITER,XT,EOL,MSG,SB,GREP,HISTORY,LP.
    23-046 Blocked lines do not follow a SWL.

    Discussion :

    If Open/ed crashes and is restarted, it may start a new shared memory segment for alarms.
    The only way around this is to exit all of your Open/ed sessions and
    remove the control file : %alarms.control.file%.

    The WHICH command examines each directory in PATH.
    If '*' is specified and the same directory is also specified, then the
    WHICH command will double report if the command is found.

    The integer value of a control character is ^X.
    Quoted control codes needs a review.
