New Functions in Version V4.02

Parameters which Differ from One Another Only in their Use of Upper and Lower Case Characters

Conflict:

Source files containing such interfaces can no longer be compiled without errors. Blocks with such interfaces can be opened, but access to the second of these parameters is no longer possible. When you try to access the second parameter, the program automatically returns to the first parameter when the block is saved.

Remedy:

To check which blocks contain such conflicts, it is advisable to generate a source file for all the blocks of a program using the function ªGenerate Source File.º If errors occur when you attempt to compile the source file you have created, a conflict is present.

Correct your source files by ensuring that the parameters are unique; for example, using the Search/Replace function. Then compile the files again.

Symbols which Differ from Parameters Only in their Use of Upper and Lower Case Characters

Conflict:

If shared and local symbols in a source file only differ from one another in their upper and lower case characters, and if no initial characters have been used to identify shared (ªsymbol nameº) or local (#symbol name) symbols, the local symbol will always be used during compilation. This will cause the machine code to be modified.

Remedy:

In this case it is advisable to generate a new source file from all of the blocks. This will automatically assign local and shared access with the corresponding initial characters and will ensure that they are handled correctly during future compilation procedures.
