Parameter types
The following parameter types are supported:
- bool
- type that can have two values: true or false
- int
- a member of the set of whole numbers
- real
- a member of the set of rational and irrational numbers
- string
- sequence of characters
- directory
- name of the location of a list of files on a storage device
- file
- name of any file
- dataset
- name of a SAS data file
- block
- general type for a section of data within a dataset
- table
- a block in a dataset, interpreted as a table
- array
- a block in a dataset, interpreted as an array
- column
- a column of data within a table of a dataset
- angle
- type that allows different formats of angle specification
- time
- type that allows different formats of time specification
Each parameter may be specified to contain either a scalar (single) value or a list of values:
- listbool
-
- listint
-
- listreal
-
- liststring
-
- listdirectory
-
- listfile
-
- listdataset
-
- listblock
-
- listtable
-
- listarray
-
- listcolumn
-
- listangle
-
- listtime
-
The use of different types allows the parameter interface to check that the
value is syntactically correct and, where appropriate, within an allowable
range. It also allows the GUI to provide appropriate widgets for entering
the values.
For example, a file-name is simply a string, as far as the task is concerned.
However, using a separate type allows the GUI to present the user with a file
dialog, instead of a simple string-edit field.
