Screen form elements

Main body
of the form
Screen form elements fill lines in the main body of the form. One or several screen
form elements can be defined in each line (see also "Multi-column screen forms").
The term "screen form element" refers to the visible part of a variable, i.e., short
text, graphics text, input/output field (I/O field) and unit text.
All variables are valid only in the active screen form. Properties are assigned to a
variable when it is defined.
The values of form screen properties can be accessed within methods (e.g., a
PRESS block). See Subsection 3.3.9.
