No Sir, That day told me to do so, but I was wondering how it will be done. I will create multiple copy of my DLL like ps2pdf-2.dll, ps2pdf-3.dll but What is to be done next. Here is my example Can you please Exemplify me.

Local loMyObject
loMyObject = CreateObject("MyObject")
loMyObject.Mainprocess()
Return

DEFINE CLASS MyObject AS Custom
PROCEDURE Mainprocess
Local Parallel as Parallel
Parallel = NewObject("Parallel", "ParallelFox.vcx")
Parallel.SetWorkerCount(Parallel.CPUCount)
Parallel.StartWorkers()

SCAN
iFilename=ALLTRIM(Fullpath)
oFilename=ALLTRIM(Newpath)
RCNON=Recno()
Parallel.CallMethod("ps2pdf", This.Class, This.ClassLibrary,,,iFilename,oFilename,RCNON)
ENDSCAN
ENDPROC

** Convert ps files to PDF Using ps2PDF.Dll
PROCEDURE ps2PDF
PARAMETERS iFilename,oFilename,RCNON
DECLARE INTEGER _apCreate@0   IN ps2pdf.dll AS apCreate
DECLARE         _apClose@4    IN ps2pdf.dll AS apClose   INTEGER id
DECLARE INTEGER _apConvert@4  IN ps2pdf.dll AS apConvert INTEGER id
DECLARE INTEGER _apSetFunc@24 IN ps2pdf.dll AS apSetFunc INTEGER id, INTEGER code, INTEGER nOptVal1, INTEGER nOptVal2, STRING pOptVal1, STRING pOptVal2
DECLARE INTEGER _apGetFunc@24 IN ps2pdf.dll AS apGetFunc INTEGER id, INTEGER code, INTEGER nOptVal1, INTEGER nOptVal2, STRING pOptVal1, STRING pOptVal2
#define AP_Set_Output     3000
#define AP_Set_Input      3001
id=apCreate()
IF (id # 0)
apSetFunc(id, AP_Set_Input , 0, 0,iFilename, 0)  &&input file.
apSetFunc(id, AP_Set_Output, 0, 0,oFilename, 0) &&output format and file.
apConvert(id)
apClose(id)
Sys(2335, 1)	&& disable unattended mode, allow UI
WAIT WINDOW 'Converting to PDF..'+ALLTRIM(STR(RCNON)) NOWAIT
ENDIF
ENDPROC
