示例1: arrayErrorCheck
//
// Do all the semantic checking for declaring an array, with and
// without a size, and make the right changes to the symbol table.
//
// size == 0 means no specified size.
//
// Returns true if there was an error.
//
bool TParseContext::arrayErrorCheck(int line, TString& identifier, TPublicType type, TVariable*& variable)
{
//
// Don't check for reserved word use until after we know it's not in the symbol table,
// because reserved arrays can be redeclared.
//
bool builtIn = false;
