wait for file creation

I am trying to get a lisp routine to pause until a pdf is created before renaming it as part of a plotting routine.

Im probably miles out but any help would be appriciated.
end portion of routine listed below.

(setq testfile (dos_filep "c:\\My Documents\\plotfiles\\tempplot.pdf"))
(while (= "nil" testfile)
(command "delay" 2000)
(setq dop (dos_filep "c:\\my documents\\plotfiles\\tempplot.pdf"))
)
(dos_delete pdfnewname)
(dos_rename pfdoldname pdfnewname)
(setvar "tilemode" oldtile)
(princ)
)

Thanks

Spence

 

sorry that should be

(setq testfile (dos_filep "c:\\My Documents\\plotfiles\\tempplot.pdf"))
(while (= "nil" testfile)
(command "delay" 2000)
(setq testfile (dos_filep "c:\\my documents\\plotfiles\\tempplot.pdf"))
)
(dos_delete pdfnewname)
(dos_rename pfdoldname pdfnewname)
(setvar "tilemode" oldtile)
(princ)
)

 

Couldn't you just name the file with the correct name when you plot it?
Seems to me like it would save some time and code.

Im sorry ive mislead you, The PDF creators available on freeware are very limited in the filenaming options allowed, This is part of a routine that extracts attributes from a title block and names the file from there, I have tried to find a way to incorperate this into the pdf creator but cant, Its not a major problem, I have got the program working by simply putting a delay in but this seems a bit shabby.
