[SYMPTOM]
When debugging an overlaid program with symbols, the symbol
table can disappear after a link is brought in.
**********
[DIAGNOSIS]
As links are deleted and brought in, the overlay handler also
maintains the symbol table to reflect the links currently in
memory. This also involves maintaining the JOBDAT symbol table
pointer, .JBSYM, as the symbol table moves around. However, DDT
does not look at .JBSYM, but only believes its own internal symbol
table pointer. Therefore, even though the overlay handler properly
updates .JBSYM, DDT never notices it.
**********
[CURE]
Until there is a standard for the location of the symbol table
pointer, do what the EXEC does when it brings in DDT -- track down
DDT's internal symbol table pointer and change it whenever .JBSYM
is updated in the overlay handler.

**********
[SYMPTOM]
Multiply defined globals or run-time errors result with LINK
overlays when FORLIB routines with the same names as JSYS names are
called.
**********
[DIAGNOSIS]
This error results because the JSYS names are defined in MONSYM as
global symbols, and are not defined with the usual . or % in the
name to avoid such conflicts. Subsequent use of these JSYS names
by the overlay handler cause the conflicts with the similarly named
FORLIB subroutines.
**********
[CURE]
Make JSYS names be of the form NAME%, then change the overlay
handler to use the new names. The JSYS name change is addressed in
a separate patch to MONSYM.MAC, which is attached. The patch
directly below then changes the overlay handler to use the new
names. Note that sites wishing to save themselves a lot of work
may simply change over the names of just those JSYSes that cause
the conflicts.

[SYMPTOM]
The overlay handler does not have the same conditional names as the
rest of LINK. In particular, OVRLAY.MAC uses the FTENEX
conditional name rather than TOPS20 which the rest of LINK uses.
Also, the overlay handler does not use mnemonics for JSYS
arguments, making the code harder to read.
**********
[DIAGNOSIS]
OVRLAY.MAC was missed when the FTENEX conditional name was changed
to TOPS20 in the rest of LINK.
**********

Use TOPS20 as the conditional name rather than FTENEX, and use the
proper mnemonics for JSYS arguments.

[SYMPTOM]
Various errors can occur when attempting to delete a link in an
overlaid program. In particular, the following cases fail:
1. Calling REMOVL with a superior link name causes that link
to be deleted without an error message. Deleting a link
implies deleting all of its inferior links (including the
caller of REMOVL in this case), which is a user error, but
which REMOVL does not do.
2. Calling RUNOVL with the name of a link that would overlay
the calling link should succeed (since no return to the
caller is ever made), but does not. This is contrary to
the LINK documentation.
**********
[DIAGNOSIS]
1. There are two reasons for the REMOVL problems. First,
REMOVL is not deleting all of a link's inferior links,
along with the requested link itself. Second, REMOVL only
gives the OVLARC message if the caller is explicitly
requesting to delete itself.
2. The same (incomplete) checks are made in RUNOVL as in
REMOVL. This is incorrect, since RUNOVL should allow
overlaying of the calling link.
**********
[CURE]
To solve the above problems, several changes were made that could
Digital Equipment Corporation 28-AUG-79 Page 33
PCO Log Report
potentially affect user programs. First, REMOVL was changed to
take exactly a single argument (as documented) rather than a list
of arguments. The specified link and all of its inferiors are then
removed. If this results in the calling link being removed, then
the OVLARC message is printed. Note that since REMOVL deletes a
link and all of its inferiors, it is not necessary to have it take
multiple arguments (simply specify the most superior link), so
exactly one argument is now required.
Second, RUNOVL has been made to allow deletion of the calling link,
and in fact superior links (back to the level of the link to be
run), since the link to be run is not allowed to return.

[SYMPTOM]
Various problems with argument checking in the manual call
subroutines (e.g., GETOV., REMOV.):
1. Not all of the defined single and double precision
argument types are accepted by the manual call
subroutines. One example of this is that CALL GETOVL("1)
fails in FORTRAN, since the argument is marked as octal by
FORTRAN and octal types are not accepted by the overlay
handler.
2. The OVLIAT message (illegal argument type) prints junk for
the routine called, and the wrong PC of the caller.
**********
[DIAGNOSIS]
1. The overlay handler was designed before the more exotic
types were added, and was never told about them.
2. Edit 10 was supposed to fix this problem, but the reasons
for its failure are lost in history. Currently, the code
is using the wrong stack offset to find the call to the
manual routine, causing it to look in the wrong place for
the name and the calling PC.
**********
[CURE]
1. Allow all currently defined single and double precision
argument types to be valid for the overlay handler.
Digital Equipment Corporation 28-AUG-79 Page 40
PCO Log Report
2. Make the overlay handler's type checking error routine
look in the right place for the routine name and calling
PC.

[SYMPTOM]
Push-down overflows occur when running (via calls to RUNOV.)
overlays many times.
**********
[DIAGNOSIS]
Each time RUNOV. is called to run an overlay, it leaves a word on
the stack. This adds up and can result in a push-down overflow if
enough calls to RUNOV. are made.
**********
[CURE]
See that the overlay handler leaves nothing of its own on the stack
when running an overlay. This can be done because overlays that
are run with RUNOV. are not allowed to return.

[SYMPTOM]
The runtime overlay handler cannot find the overlay
file when the overlaid program has been run from an SFD.
This problem is worse under 7-series monitors, since the
overlay handler can't even find the overlay file when the
default path is set into an SFD.
**********
[DIAGNOSIS]
Under monitors before 7-series, the information is not
available. However, new GETTABs in the 7-series monitors
make it possible to fully support SFDs in OVRLAY.
**********
[CURE]
If the GETTABs are available, use what they return to
find the overlay file. If not, use FUNCT. as in the past.
