The library SysLibDirect.lib

The functions of this library serve to access variables by indices with which they are referenced in the runtime system. For detailed information see the description of the particular runtime system.

The user does not have to call a function! The functions will be called implicitely, according to the data type and the access mode of the variable, as soon as the library is linked to the project and a variable will be used in the program with the “#” like shown in the following:

iVar1 AT #MW17.4: INT;

The functions must be implemented in the runtime system as external C-functions.

The execution is synchronous.
