I try to port an old DOS app that mainly used plain old text + few 
simple graphics to a windows console mode using BCC32 5.5.1

1. i still get linker unresolved references which come from calls by 
functions of the standard library (not my calls); or perhaps these are 
internal variables ?
I linked with c0x32.obj, cw32.lib and import32.lib; Is there another 
library/obj i have to add when linking ?
_CG_DA_BEPXSY
_CG_INTR_STRCPY
_CG_LDA_EOXSY
_CG_GDA_EGY
_CG_A_PY
_CG_A_PQ
_CG_DA_EPY
_CG_A_BP
_CG_GDA_EGXSY
_CG_DA_EPXSY
are unresolved

2. Are there any equivalent functions of the graphic functions that were 
in the graphics.lib under bcc 3.1 ?
like : line(), moveto(), rectangle(), setcolor(), outtxtxy()... which 
worked in a dos box

Thank all of you for your help

The _CG_* unresolved references are for CodeGuard.  Something that you are 
linking with or some source of yours is trying to use CodeGuard.  Fix that.

Those are Borland Graphics Interface, BGI, functions.  They are a DOS based 
attempt to provide some of the graphical abilities that Windows natively 
supplies.  The C++ Builder compiler you are using does not support DOS.  It 
only supports 32 bit Windows.  Use the Windows API for doing graphics.
