[ts-7000] Re: Strange shifting variables

["Andy Mercier" <>]

Hi Eric,

I'm going to try to help but this'll quick so it may not be perfect
but may get you going in the right direction so that I or others on
the list can help out better.

Looks like your sample of your code needs improvement. Did you mean:

struct s {
 int var1
 int var2
 };

void caller()
{
   struct s the_struct;

   callie(&the_struct);
}

void callie(struct s *s)
{

// switch (something) {  // Doesn't matter for troubleshooting
//  case 0: // Ditto
    s->var1=4;
    s->var2=20;
//    printf("%d  %d\n", var1,var2); // Your code
    printf("%d  %d\n", s->var1, s->var2);
//    break; // Doesn't matter for troubleshooting
//  default: // Ditto
//    break; // Ditto
// } // Ditto
// printf("%d  %d\n", var1,var2); // Your code
   printf("%d  %d\n", s->var1, s->var2);
}

BTW, is is a general programming problem and not specific to any TS
product.

Happy to help.
