18.5 Menu Variables
The range variables are very useful, e.g., if one wants to select several files from consecutive
sessions. Range variables may be used for widgets where a list of values may be specified
(more than one input file for the widget selwin or a range of sessions to specify a time
window).
Note that the menu time variables always refer to the sessions as defined in the session
table. This must not necessarily be days (especially for a fixed session table or an open
session table with more than one session per day). E.g., for a fixed session table the variable
$S+1 is undefined if $S+0 refers to the last session in the table. For an open session table,
however, $S+1 refers to the next session in the table which may be the first session of the
following day. For more examples and details we refer to the online help.
18.5.2 User Variables
The user may define an arbitrary number of variables using the uniline widget “USER-
DEFINED VARIABLES” in the first of the menu variable panels (”Menu>Configure>Menu variables”,
see Figure 18.3). In this example the variable $(DAY) is translated by the menu system to
WEDNESDAY wherever it is used. For 1-character variables the brackets are not necessary
(you may, e.g., use $R in an input field). For variables with more than one character the
brackets are mandatory to get an unambiguous variable names. The user-defined variables
may be used in all widgets where menu time variables are permitted. Be aware that the
variable names are case-sensitive.
The variables $Y, $M, $D, and $J are predefined (see previous Section) and are reserved.
They may not be used as user variables.
