INPUT

Syntax: INPUT(var,[“title”], [“label”], [“help”], [reset_value],

[initial_value])

Syntax: INPUT({vars},[“title”], [{“labels”}], [{“help”}], [{reset_values}],

[{initial_values}])

The simpler form of this command opens a dialog box with the given title and one eld named label,

displaying help at the bottom. The dialog box includes the CANCEL and OK menu keys. The user can enter a

value in the labeled eld. If the user presses the OK menu key, the variable var is updated with the entered

value and 1 is returned. If the user presses the CANCEL menu key, the variable is not updated and 0 is

returned.

In the more complex form of the command, lists are used to create a multi-eld dialog box. If var is a list, each

element can be either a variable name or a list using the following syntax.

●

{var_name, real, [{pos}]} to create a check box control. If real is >1, this check box gets pooled with the

next n -1 check boxes in a radio group (that is, only one of the n check boxes can be checked at any time)

●

{var_name, [allowed_types_matrix] , [{pos}]} to create an edit eld. [allowed_types_matrix] lists all the

allowed types ([-1] stands for all types allowed). If the only allowed type is a string, the edition hides the

double quotes.

●

{var_name, {Choose items}, [{pos}]} to create a choose eld.

If pos is specied, it is a list of the form {eld start in screen %, eld width in screen%, line(starts at 0)}. This

allows you to control the precise position and size of your elds. Note that you have to specify pos for either

none or all elds in the dialog box.

There is a maximum of seven lines of controls per page. Controls with more than seven lines are placed in

subsequent pages. If more than one page is created, ["title"] can be a list of titles.
