To locate based variables, use the value of the defining pointer.
Find this value by using one of the methods described above to find
static and automatic variables. If the pointer is itself based, you
must find its defining pointer and follow the chain until you find
the correct value. The following is an example of typical code for
X BASED (P), with P AUTOMATIC:
58 60 D 0C8 L 6,P
58 E0 6 000 L 14,X
P is held at offset X'C8' from register 13. This address
points to X.
Take care when examining a based variable to ensure that the pointers
are still valid.
