Forms-Control Statements
A 4GL application involves the display and manipulation of data that the application user sees on forms in the window. Through forms-control statements, you can manipulate both form fields and local variables. You can use forms-control statements to:
• Position and move the cursor on the form
• Set the display mode of the form
• Clear the screen or clear individual fields
• Provide help text, display messages and prompts
• Validate data fields
• Manipulate individual table field rows or array records
• Process an entire table field or array at once
• Display additional operations on submenus
You can include forms-control statements as part of initialization or place them throughout the 4GL specification.
