Hey, it works. Thanks.

Also, forgot to add: in version two (of mine), the compiler also
optimises out the "bob := 0;" line.

How about this?

procedure Samuel([arguments]);
var
  bob: Integer;
begin
  ...
  if [condition1] then
    bob := 1
  else if [condition2] then
    bob := 2
  else if [condition3] then
    bob := 3
  else
  begin
    raise Exception.Create('error message');
    bob := 0; // added this line to get rid of warning
  end;
  jim := bob + 10;
  ...
end;

I've got another one that I found funny:

procedure Samuel([arguments]);
var
  bob: Integer;
begin
  ...
  if [condition1] then
    bob := 1
  else if [condition2] then
    bob := 2
  else if [condition3] then
    bob := 3
  else
    raise Exception.Create('error message');
  jim := bob + 10;
  ...
end;

gives the warning "Variable 'bob' might not have been initialized" on
the line "jim := bob + 10". Which is true, even though if bob has no
value then the exception will prevent that line of code from being run.
But, if you change the code to:

procedure Samuel([arguments]);
var
  bob: Integer;
begin
  ...
  bob := 0; // added this line to get rid of warning
  if [condition1] then
    bob := 1
  else if [condition2] then
    bob := 2
  else if [condition3] then
    bob := 3
  else
    raise Exception.Create('error message');
  jim := bob + 10;
  ...
end;

then you get a hint "Value assigned to 'bob' never used".
