I like the stronger checks of the X# compiler

Hi,

compiling this code:

Code: Select all

nLen := oParameter:Count - 1
for nI := 0 upto nLen                                                   
  cKey:= cKey
  cParameter:Replace( "@" + cKey + "@", oParameter[cKey] )
next

gave me the compiler warnings

warning XS1717: Assignment made to same variable; did you mean to assign something else?
warning XS0165: Use of unassigned local variable 'cKey'

and in fact, the compiler is right!

Thank you for discovering such (stupid) errors!

Hi Wolfgang,

Actually the X# compiler found this exact problem also in my old VIDE code, about a dozen times! In all cases it was of course bugs in my code that were not caught by the vulcan compiler earlier and were causing incorrect runtime behavior, was embarrassing to realize this after all that time

There were more similar problems in my code (about 135k lines) that were pointed out by the X# compiler, I want to find some time and write a blog article about this.

Hi Chris,

new and stronger compilers help us programmers to write more stable programs - I like them.

Thanks to your team for this check!
