scalar_value

`scalar_value`

A single numeric value — literal, named scalar, or an indexed component of another coordinate_list.

Kind: concept

You can use a scalar_value as an expression in the following ways:

Specifying the scalar name/value directly -- in this case, all values in the coordinate_list get this value. For example:
```
   set foo 1.0
     and
   set foo [1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0]
...or
   set foo h
     and
   set foo [h h h h h h h h]
```
are equivalent.

You can specify a scalar as a sparse coordinate_list by using the following syntax:

   scalar@x or scalar@0
   scalar@y or scalar@1
   scalar@w or scalar@2
   scalar@h or scalar@3
   scalar@ls or scalar@4
   scalar@ts or scalar@5
   scalar@rs or scalar@6
   scalar@bs or scalar@7

For example, the following are equivalent:

   set foo 1.0@w
     and
   set foo [0 0 1.0 0]
...or
   set foo recarm@w
     and
   set foo [0 0 recarm 0]

As a shorthand for making a sparse coordinate_list from one value of a coordinate_list, "coordlist{x}@x" can be abbreviated as "coordlist@x".
