Input through input forms

Function INFORM („°L@)@@IN@@ @INFOR@.) can be used to create detailed

input forms for a program. Function INFORM requires five arguments, in this

order:

1. A title: a character string describing the input form

2. Field definitions: a list with one or more field definitions {s

… s

where each field definition, s

, can have one of two formats:

a. A simple field label: a character string

b. A list of specifications of the form {“label” “helpInfo” type

type

… type

}. The “label” is a field label. The “helpInfo”

is a character string describing the field label in detail, and

the type specifications is a list of types of variables allowed

for the field (see Chapter 24 for object types).

3. Field format information: a single number col or a list {col tabs}. In

this specification, col is the number of columns in the input box, and

tabs (optional) specifies the number of tab stops between the labels

and the fields in the form. The list could be an empty list. Default

values are col = 1 and tabs = 3.

4. List of reset values: a list containing the values to reset the different

fields if the option @RESET is selected while using the input form.

5. List of initial values: a list containing the initial values of the fields.
