Hello there ^^
Which command interpreter are you going to use ?
If it's compatible with Windows XP's cmd, you may try that :
FOR /F "usebackq" %%a in (`dir /b R:\*.gho`) DO R:\ghost -clone,mode=load,src=R:\%%a,dst=1, -afile=C:\ghststat.txt -sure -FX
Assuming there is only one .GHO file in your R:\ directory.
Also, I don't own ghost so I can't check much about it.
