Error message: "abort is not in the set AllIdentifiers".

Hi everybody, 

 

Recently I updated AIMMS to version 24.6.1.6. Now I get the error message “The element 'abort' is not in the set "AllIdentifiers", see also the option warning_explicit_element_not_in_set.”. Does anyone know how I can solve this error? 

 

It happens when I use a call back function and want to assign “abort” to the CallBackReturnStatus. 

 

Thank you in advance!

Hello!
From which version of AIMMS are you migrating from?

What I can see for  CallbackReturnStatus is that "The value of the .CallbackReturnStatus suffix is an element in the set ContinueAbort.”

https://documentation.aimms.com/functionreference/suffices/mathematical-program-suffices/callbackreturnstatus.html

Looking at ContinueAbort that it is a subset of AllValueKeyword, which is not a subset of AllSymbols or AllIndenfiers 

https://documentation.aimms.com/functionreference/predefined-identifiers/language-related-identifiers/continueabort.html

If you are using an element parameter to set the callback status, maybe you can change the range of that to ContinueAbort ?

Maybe some code sample can help figure what is going on.

Best regards

Maybe try to single quote abort, as in ‘abort'. We've been gradually replacing the compiler, and most likely the new compiler is more picky wrt quoting set elements.

Thank you ​@luispinto and ​@MarcelRoelofs! I had a very old version of AIMMS (4.98). 

 

An example:

if (abs(capacitatedNoSkill.Incumbent - capacitatedNoSkill.Objective) <= 1000) then
    capacitatedNoSkill.CallbackReturnStatus := 'abort';
endif;

 

Best regards

@C123 The bug causing this issue has been fixed in AIMMS 25.4.2.
