In case of the PM Debugger, IPMD.EXE, you would use SBCS PM Debugger on DBCS environment to debug your program on the real DBCS environment. In such case, you need to change the process code page to SBCS code page with CHCP or CHGCP command. However, if you need to debug program portion related to the process code page, e.g. logic for loading appropriate MRI or DBCS character input, this might disturb you in debugging. You need DBCS version to debug such portion.(**)
