Re: Informix C-compiler Version does not initialize variables?

Fix your code to initialize your variables. The p-code compiler does that for you -- arguably this is a bug, because the C compiler definitely doesn't. This is probably the biggest unresolvable difference between the p-code and c-code run-time systems. > There is something wrong here because this code worked on c4gl > version 4 4gl on AT&T Unix SysV3.2 with version 4 SE. Pure coincidence -- there just happened to be a zero byte at the correct location. You were unbelievably lucky. Well, maybe not unbelievably, but definitely lucky.
