In addition to scalar variables, MIIS also has single dimensional arrays $($among others$).$The rules for naming arrays are the same as the rules for. naming variablesUnlike almost allother programming languages, there is no need $($and no capability$)$ for declaring array dimension. An element of an array is undefined untilyou put something into it$.$ The system only has to allocate space for those array elements which are definedThere is also no restriction on the data types of different array elements. Thus you can have string and numeric values within the same array.Suppose the only variables defined are:$0($OA$()32767$A$(100)=$ "NINETY$-$NINE"A$(32767)=$ "THIS IS A STRING"What is the value of the following expression: A $($A $($A$+1))$UNDEFINED$327670$"THIS IS A STRING"
