SHOW command

Syntax: | `SHOW v1 { v2 ... }`
Qualifiers: | `\SCALARS, \VECTORS, \MATRICES, \TEXT, \FIXED, \FIT`
Defaults: | all variables displayed

The `SHOW` command displays: the current scalars, their values and histories; the current vectors, their lengths and histories; the current matrices, their dimensions and histories; and the current text variables, their lengths and contents.

If a variable name is entered, only the information about that variable is listed.

Valid wildcard usages are (where x represents one or more characters):

`*x` | → | all variables that end with `x`
`x*` | → | all variables that start with `x`
`*x*` | → | all variables that contain `x`

Qualifiers

If the `\VECTORS` qualifier is used, vectors will be listed.

If the `\MATRICES` qualifier is used, matrix variables will be listed.

If the `\TEXT` qualifier is used, text variables will be listed.

If the `\SCALARS` qualifier is used, scalar variables will be listed.

The following qualifiers are only valid when used with `\SCALARS`.

`\-FIXED` | --> | do not show scalars that are fixed (with respect to fitting)
`\-FIT` | --> | do not show scalars allowed to vary in a fit
