= Execute edit command file.

        EXE  [!] { * | ^* | filename } [parm-1,...] [.lab1 .lab2]
                   [< {@parmfile | [S] wildcard  [D[+]] ]

         !       :execute all cmd in the file ignoring each cmd error.
                  ! is specified each line in the cmd file.
         *       :execute command in the currently displayed file.
         ^*      :execute command file opened in the other side of
                  split screen.
         filename:file contains edit commands.
                  accept notation *\, ^*\ or :: etc.
                  comment line is start by "#".
                  "#" after ";" also start comment description.
         parm-n  :parms replace %1--%9 in the command file.
        .lab1/2 :limit line range using label line cmd or lineno.
                  ex) EXE * .from .to; EXE ^* .120 .130
         Parameters after "<" enable to repeat the EXE cmd until all entry are exausted.

         @parmfile :Repeat for each line of the parmfile.
         S         :S means select and used on the dir-list panel.
                    Each filename(with out path) corresponding to the wildcard is the last parameter to the EXE cmd.
         wildcard  :Without "S",fullpath name corresponding to the wildcard is the last parameter
                    of each repetation.
         D[+]      :By default,sub dir is not selected.
                    D : select directory entry only, D+:select all entry including directory.

            One supposed usage is change the word in all files in the directory at once.
            ex) File execmdf contains following 3 lines.
                       s "%3"
                       c %1 %2 all
                       end
                Enter  "exe ! execmdf FROM TO <s *.c" on dir-list panel.
                EXE cmd executes Select/Change/End to all *.c file in this directory.
                If "!" is not specified, repetition stop at the file which dose not contains the word FROM.
                To abridge cmd input,you may register this exe cmd in =0.1 panel.
                For ex,enter "chd exe ! execmdf %1 %2 <s *.c" on =0.1 panel.
                "chd FROM TO" on cmd line do the same thing.
            When set-upping EXE cmd file, you should consider that file name may have embedding space.
            EXE cmd log remains on ::#exe.

        -Command is optionally logged to file "::cl" by "OPT CMDLOG [ON|OFF]"
         ::cl may be used to create EXE cmd file.
         (for OS/2 or GCC,once close by "OPT CMDLOG OFF",then open ::cl)


        -AT and SLEep command is not avail in the file.

         -sample command file
                swap
                reset x
                x all
                i %1 all
                i %2 all
                del x all
                s %3
