VARIABLES

There are two kinds of variables in the macro language : o User variables that are handled in macros o Contexts that hold the different internal states of the program In all cases, variable names are case insensitive. User variables : can be set : set a = 3 evaluated : $a (directly) ($a+3) (or in expressions) Variables are usually lcal to a macro (or a formbox), unless specified : set b := 4 creates a variable $b that can be evaluated anywhere, (static and global) Associative array can be built with the syntaxe : set array["abc"] = 5 Associative arrays can be linked to dbm data file (see DBMOPEN) Associative arrays can be scanned with FIND or FOREACH User variables can also be UNSET (rmoved from the memory) The total number of user vatiables is limited, as given by the CONFIG command On the other hands, contexts can only be evaluated, but not set: if ($dim != 2) .... see CONTEXTS for the list of all the context variables

VERBOSE

When this context is set to 1 the program switches to a more verbose mode. Specially, text output will be generated during macro execution, during MaxEnt run and during LP execution. When verbose equals to 0, no text is generated.
see also : DEBUG


VERT

vert i j In 3D mode, extract a column orthogonal to the last displayed plane. The column is taken at coordinates i and j in this plane.
see also : COL DIM PLANE planeint ROW vertint


vertint

interactive permits to choose verts interactively on a 3D by clicking on the 2d plane
see also : COL colint ph2dc planeint ROW rowint


VHEIGHT

This context is used when displaying or plotting 1D spectra, it determines the level at which the zero value will be displayed in the window. Values are in %, i.e. 0 corresponds to the bottom line and 1 to the top. Default value is 0.3

vi

as in unix
see also : CD ls more pwd rm SH vim vip


vim

open with vi a macro in the standard place i.e. in /usr/local/gifa/macro/
see also : CD ls more pwd rm SH vi vip


vip

open with vi a macro in the $HOME/macro directory
see also : CD ls more pwd rm SH vi vim
