Change RNF ID & help text for global array starting with TAB

I ran into an issue yesterday where I created a global variable as an array. The variable name was Table_Title.

When I attempted to access the array using an element ID (ie. Table_Title(1)), the compiler would throw an RNF0528 "The index is not allow for variable <whatever> that is not an array; index is ignored".

I spent a good amount of time trying to assure there were no typos, checking outline views within RDi, etc. This did not occur when Table_Title was defined as a local variable.

Then it dawned on me that TAB as the first three characters are reserved for compile-time arrays/tables.

I'd like to request that a different RNF error ID be given, with expanded text stating that the array cannot start with TAB (phrased more appropriately of course).

It would have saved me a lot of time trying to figure out where my error was.

Use Case:

    IBM believes that the request described has been solved and is available with release 7.5 of the RPG compiler product 5770WDS.

    For the following program, the RPG compiler now issues severity-20 message RNF0752, with the following text: "The name for table TABLE_TITLE begins with TAB, so is not allowed; the index is ignored."

    dcl-s Table_Title varchar(100) dim(20);
    Table_Title(1) = 'Hello';

    If OPTION(*SECLVL) is specified for the compile, the full text of the message incudes the following additional information:
    "When a variable is defined with the DIM keyword, and the name of the variable begins with TAB, the variable is considered to be a table, not an array. An array index is not allowed for a table."

    IBM agrees with the request and a solution appears to be desirable and feasible. IBM intends to provide a solution in a future full release. However, IBM's plans may change and no commitment is made that a solution will be provided.

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.
