Optional control statements can precede a panel to specify the particular requirements for that panel. These are:
Defines alternative field names
Defines the action to be taken for an error condition
Defines or modifies a field character's attributes
Provides installation documentation (this is ignored during processing)
Defines optional operational requirements
Defines trailing lines for the panel
Control statements included within panel definitions must precede the displayable portion of the panel which is determined by the first line that is not a control statement. Control statements must start in column 1 of the lines on which they appear.
Note: You cannot include comments on the same line as a control statement (except #NOTE).
