## q define

`q define varname`

This command returns information about a defined variable, `varname`. The `'q define'` command without the variable name will return a list of defined variables. When a variable name is added, the printout includes the type, the sizes of each dimension, axis definitions for each dimension, the calendar, and whether the variable has been `'modified'`.
