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.
