a$ = a$ + STR$(3)

I'm not familiar with QB, but it looks like you are trying to add something to an existing string.  If that is the case, you have two options.

1) If you are adding a string to another string, use the strcat function.

2) If you want to add a number to a string, copy the original string to a temporary string, and then use sprintf.

The reason you copy to a temporary string is that according to the C Standard, you cannot use the same string as both the target and source with sprintf.
For example, the following will compile, but may cause your program to crash.
sprintf(aString, "%s %i", aString, aNum);

So, given an array of characters called aString, a temporary array called aTemp, and a number aNum, you could do the following:

strcpy(aTemp, aString);
sprintf(aString, "%s%i", aTemp, aNum);
