3.3.1

Define a screen form

A screen form is part of a user interface consisting of a display line, form elements
and/or graphic, dialog line and 8 horizontal and 8 vertical softkeys.
The definition of a screen form (form definition block) is basically structured as
follows:
Start identifier of form
Variables
Softkeys
Methods
Actions
End of method
End identifier of form
Within the screen form definition block, various variables that appear as form
elements in the screen form, as well as horizontal and vertical softkeys, are defined
first.
Different types of actions are then configured in methods.
The following rules must be observed when configuring screen forms:
• Texts/strings, path names and system or user variables must always be
enclosed in quotation marks (" ... ").
• The Identifier parameter must be unique and always comprises a minimum of 2
and maximum of 32 characters. The first two characters must be two letters or
an underscore and a letter (a-z, A-Z, _).
• The system does not distinguish between upper and lower case type.
