Local Variables and Hidden Columns
Local variables and hidden table-field columns contain data that the application manipulates, but are not displayed on the form. These components are useful for holding information that the user does not need. While they are invisible and inaccessible to you, they are accessible to the application in the same way as displayed fields and columns.
Local variables and hidden columns are limited in scope to a single frame or procedure, while global variables are global in scope for the application. You declare data types for variables as follows:
• Declare the data types of global variables through the frames associated with the ABF Globals menu item.
• Declare the data types of local variables and hidden columns in 4GL statements. This section describes local variable declaration in 4GL specifications.
