Debug value of pointer

When debugging ILE RPG code, to see what a pointer is pointing to, you can use :x or :c when using the EVAL debugger...

command on the pointer itself. This means you can debug a pointer's value without having an RPG BASED variable.

This shows the first 10 bytes that "ptr" is pointing to, as character data: ===> EVAL ptr:c 10

This shows the first 10 bytes that "ptr" is pointing to, in hex: ===> EVAL ptr:x 10

This is useful when the pointer is pointing to data that is not readable as character data--for example, packed data. If ptr is pointing to a packed field with the value 12345, ptr:x 3 would show you X'12345F'.
