Post by janber on REFERENCE TO in an array ^{CODESYS Forge talk (Post)}
Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

Post by apurv on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
I have a Array of constant size defined like this Var Constant MAX_SIZE :UINT := 10; End_var VAR array : ARRAY[0..MAX_SIZE] OF INT; END_VAR Now I want to pass this array to a function by reference, Function fun : INT VAR_IN_OUT CONSTANT MAX_SIZE : UINT; END_VAR VAR_INPUT array : REFERENCE TO ARRAY[0..MAX_SIZE] OF INT; END_VAR but when I run this it gives strange Errors Error : Cannot Convert type 'ARRAY [0..MAX_SIZE] OF INT' to type 'ARRAY[0..MAX_SIZE] OF INT'

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?
