<snip> The syntactic difference and the citation of I&T Ref. lead me to suspect that the substringer is part of the system symbol resolver, at execution time, not of the Reader/Converter. But the interpreter must make the decision, based on the second character following the symbol name. </snip>
Basically, "yes". The rule for the system symbol resolver is that a symbol followed by a substring expression is treated as asking to use a substring of the symbol. A symbol followed by something that does not meed the exact requirements of a substring expression is treated as asking to use the symbol and then use whatever characters follow. A substring expression, in this sense, does not allow for "+", so &SYM(+0) is not &SYM with a substring expression.
