Re: Parsing CL comments

I thought I had tried this same form yesterday hence the third example in my previous append but after seeing Charles' earlier response I tried again and it failed with a syntax error. Your example above also fails.

CPD0011 Qualifier missing from qualified name 'MYOBJ* '.
CPF0001 Error found on *N command.

The first /* must have either a leading or trailing space to be considered a start of comment flag. Since a space starts a new token and a space is not valid in a parameter value (unless quoted) then a parser can "know" that a comment is not allowed at that point and therefore interprets the /* as the start of a qualified name. Note that when examining the above message the complaint is about missing data after the closing slash which indicates that parser has accepted the /*Shows as a valid qualifier for the first MYOBJ and has accepted each of the remaining words as valid tokens. Thus this error must occur very early in the parsing sequence before validation of the tokens themselves occurs.
