If the above conditions are not met, the compiler will issue a diagnostic message, and the literal will not be reparsed. As a result, if there are character literals in your OPM RPG programs that fail the transparency check performed by the OPM RPG compiler, such programs will get compilation errors in ILE RPG.
In ILE RPG, if there are two consecutive apostrophes enclosed within shift-out and shift-in control characters inside a character literal, the apostrophes will not be considered as a single apostrophe. A pair of apostrophes inside a character literal will only be considered as a single apostrophe if they are not enclosed within shift-out and shift-in control characters.
