Changing the point of view in C

Qualify to the second nested block in the function sort() in sort.
```
SET QUALIFY BLOCK %BLOCK2;
```
You can do this in a number of other ways, including:
```
QUALIFY BLOCK sort:>%BLOCK2;
```
Once the point of view changes, z/OS® Debugger has access to objects accessible from this point of view. You can specify these objects in commands without qualifiers, as in:
```
j = 3;
temp = 4;
```
Qualify to the function main in the load module MAINMOD in the compilation unit MVSID.SORTMAIN.C and list the entries of table.
```
QUALIFY BLOCK "MAINMOD"::>"MVSID.SORTMAIN.C":>main;
LIST table[i];
```
