The next example uses the same DIESEL expression as the label and a portion
of the menu item. It provides a practical way to enter the current day and
date into a drawing.
$(edtime,$(getvar,date),DDD", "D MON YYYY)^C^Ctext +
\\\ $M=$(edtime,$(getvar,date),DDD", "D MON YYYY);
Also, you can use a DIESEL macro to mark pull-down menu labels or make
them unavailable. The following pull-down menu label displays an unavailable
ERASE while a command is active. The text is displayed normally when a
command is not active.
$(if,$(getvar,cmdactive),~)ERASE
You can use a similar approach to place a mark beside a pull-down menu item
or to interactively change the character used for the mark.
