mid$ statement

[jcfuller]

  This is probably a bit anal but the mid$ statement accepts a literal as the mainstring$.
There is no way a compiler can detect an issue so it has to be done with the translator. I am not very good when it comes to following the Stk$[], Ndx code.
  I know it's not a big concern but my ocd tells me a procedure should not get a literal when it wants a char*

Code: [Select]


 DIM tmp$
 DIM anal$
 tmp$ = "s'not OCD!"
 anal$ = MID$(tmp$, 3, 3)
 PRINT anal$

If you attach pain to a lesson, the lesson will be more fully learned.

MID$("What does this accomplish?",1) = "This just proves the point ... "

Robert,
  Nice Mid$ FUNCTION demo.

Kevin,
  I know, but all you need do is check for a DQ  in the midstr$ parsing and throw an error.
noob suzy coder (who did RTFM MID$ but stopped at the function and didn't make it to the statement) would be very thankful

DQ midstr$ example?

Never mind. This thread is too stupid to even to begin to comprehend.

Maybe better, is "Never mind, I'm too stupid to even to begin to comprehend this post."

I added one line to help Suzy Coder.  My earlier one-liner now throws this error:

BCX BASIC to C/C++ Translator (c) 1999 by Kevin Diggins

There remains numerous other ways for Suzy Coder to blow her foot off.
