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
1
s
2
… s
n
},
where each field definition, s
i
, 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
0
type
1
… type
n
}. 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.
