Re: Useless use of string eqby jrsimmon (Hermit) |

To summarize some of the answers above: 1. Why is this a useless use? Because eq is used to compare things. You are trying to use it to assign a value. You muse use = for that. 2. What is a void context? {$cust eq "SMC";} is a void context, because you are performing a comparison (see 1.) but not doing anything with the result. There is not context for the compare, hence it is a void (empty) context. 3. What can I do to do this better? The first reply Re: Useless use of string eq to your post by Fletch (++) explains best how to rewrite your code. Perhaps you should ask him about the whole children bearing thing...
