     67The <FONT FACE="COURIER">readexp.tcl</FONT> and <FONT FACE="COURIER">gsascmds.tcl</FONT> files contain
    6868tcl procedures that are
    6969used for more than one application, so it is convenient to place them
     
    7171or add new functionality to expgui.
    7272<P>
    73 The <TT>gsasmenu.tcl</TT> file defines the contents of the
     73The <FONT FACE="COURIER">gsasmenu.tcl</FONT> file defines the contents of the
    7474menu bar, the contents of the
    7575button bar and definitions for each command. The contents of this file
    7676are designed to be modified and extended by users, either by editing the file,
    77 or by overriding definitions in the <TT>localconfig</TT> or
    78 <TT>.gsas_config</TT> files.
    79 
    80 The important variables defined in the <TT>gsasmenu.tcl</TT> file are:

    8383This list defines the menu bar headings other than File, Options & Help
    84 <DT><TT>expgui_menulist</TT><DD>
     84<DT><FONT FACE="COURIER">expgui_menulist</FONT><DD>
    8585Each array element, e.g. expgui_menulist(file) and expgui_menulist(powder),
    8686defines commands to be added to a menu heading. Each command will appear
    8787as an array element in expgui_cmdlist.
    88 <DT><TT>expgui_cmdlist</TT><DD>
     88<DT><FONT FACE="COURIER">expgui_cmdlist</FONT><DD>
    8989Each array element, e.g. expgui_cmdlist(Save) or expgui_cmdlist(expnam)
    9090contains two items. The first defines a tcl procedure to be executed
     
    9393Note that when menu item is selected the variable cmd is set to the
    9494name of the command, so
    95 <PRE>
     95<FONT FACE="COURIER"><PRE>
    9696    expgui_cmdlist(powpref) {{runGSASwEXP $cmd} {Powder data preparation}}
    97 </PRE>
     97</PRE></FONT>
    9898means that "runGSASwEXP powpref" will be invoked when powpref is invoked.
    9999For example, when powpref is selected, the tcl command
    100100"runGSASwEXP $cmd" is invoked, where variable cmd is set to "powpref".

     101<DT><FONT FACE="COURIER">expgui(buttonlist)</FONT><DD>
    102102This list defines the commands that will appear on the button bar where
    103103each item that appears on the button bar must have a matching pair of entries
    104104in expgui_cmdlist.
    105105Thus if the command

    129129This determines where the GSAS executable files are located.
    130130You might want to change this is you keep multiple versions of GSAS
     
    133133in a subdirectory of the GSAS files.

    160160This defines the default state for the archive flag,
    161161where 0 is off and 1 is on. When archive is on, a copy of the .EXP file
    162162is saved before a new version of the file is saved in EXPGUI.

    164 <DT><TT>expgui(font)</TT><DD>
     164<DT><FONT FACE="COURIER">expgui(font)</FONT><DD>
    165165This determines the base font used in the programs. You conceivably
    166166could want to use an integer value not present in the
