Tables
- Tables are one of the most useful types of results available to users of the NeXtMidas shell and macro language. A table is a collection of values each with a unique tag (or name).
- When defined on the command line or in a macro, a table is specified in the following format:
```
nM> set mytable {TAG1=VAL1,TAG2=VAL2,...,TAGn=VALn}
```
  A table is defined within a pair of braces ({...}) and each element of the table is specified by a TAG=VALUE syntax with a comma (,) separating subsequent elements.
- All tags in a table must be one or more characters in length and may contain only numbers, upper-case letters and the underscore.
  - This differs from valid results names in that the tag can start with a number.
  - Older versions of NeXtMidas allowed names to contain a dash (-), this behavior is deprecated since it makes it hard to tell a table entry from a subtraction.

X-Midas Users Take Note:
Stable X-Midas releases before 4.6.0 do not support tables. Support for tables is added in X-Midas 4.6.0 and is called `XMVALUE`. X-Midas tables are syntactically very similar to NeXtMidas tables. Check the documentation for differences.
