What? @= in TM1? What does that mean?
Well, simply put if you have an expression that says sVariable = ‘Test’; then you are storing the value ‘Test’ into the string variable called sVariable. If you want to check if the contents of a string is equal to something, then you need to use an @ sign before the operator.
@= in TM1 Rules
Therefore we get Rule expressions like the following:
IF (sVariable @= 'Test' ,Outcome1 ,Outcome2 );
@= in Turbo Integrator Processes
Or a Turbo Integrator expression like this:
If (sVariable @= 'Test'); Outcome1; Else; Outcome2; EndIf;
Note re @= in TM1
You only need to use this operator in TM1 for string (text) based evaluation. For numbers, no @ sign is required.
