Function overloading
By patvdv at 26 Feb 2008 - 21:56

Function overloading

When DLLs are dynamically linked at runtime, instead of at compile time, function overloading is possible. This means that an external function contained in a loaded DLL can be replaced by overloading another DLL that contains a function with the same name and arguments.

4GL group sections

4GL group sections

With dynamic forms, the mapping of groups to forms is not fixed. Consequently, the only form sections that are relevant to dynamic forms are the form.all and form.1 sections. When dealing with dynamic forms, you use group sections instead of form sections

Dynamic-link libraries
By patvdv at 26 Feb 2008 - 21:56

Dynamic-link libraries

BaanERP Tools supports the use of dynamic-link libraries (DLLs). A DLL consists of a library of functions that are compiled, linked, and stored separately from the processes that use them. The functions are resources that can be shared by multiple programs that are running concurrently. Only one copy of the DLL needs to be present in memory. Each program that uses the DLL links to it at runtime, at the time it calls one of the DLL�s functions.

Scope of variables across DLLs

Scope of variables across DLLs

Global variables

Global variables are declared outside the functions in a script, without the EXTERN keyword. They are only known within the DLL in which they are declared. For example:

Symbolic constants
By patvdv at 26 Feb 2008 - 21:56


Symbolic constants

A symbolic constant is used in your program as a symbolic name, but at runtime it has a fixed value. The defined constants are:

       FALSE   The actual value is 0
TRUE The actual value is 1
PI The actual value is 3.141592653589793

Note that if FALSE and TRUE are used as boolean values (for example, as a result of expressions), they mean zero and not zero respectively.

Tables
By patvdv at 26 Feb 2008 - 21:56

Tables

If you use database tables and records in your program, you must declare the tables as follows:

TABLE <table name> | table name must start with a 't'.

This declaration creates a pointer to the table. Declaration of a table implies declaration of all its fields and its record buffer. It is not necessary to declare these separately.
