QNA        :Do Overlays work in BC++ 5.01
Category   :Linking
Platform   :Windows95
Product   :BC++  5.x

Question:
Can I create an overlayed DOS program with 5.01

Answer:

There are two overlay problems with 5.01
1) the IDE project manager doesn't pick up the local Node attributes, 
"overlay this module" correctly so /o is not passed to tlink.exe
You will not see this switch in the *.r$p file that is produced.
2) tlink.exe 7.1.32.2 (5.01) does not respect this switch anyway.
So the only resolution is to use an older tlink ( 7.0 comes with 4.52 )
and use the makefile that "Generate makefile" produces ( this does pick
up the "overlay this module" checkbox ). Or if they are committed to 
projects they will have to install 4.52.

relevant switches:
-Y compiler switch ( make this obj overlayable )
/o linker switch ( overlay toggle )
TDUMP has some friendly "this is overlayed" diagnostics.
