I was able to disassemble it (into Assembler), the EXE, that is. I am able to see that there is no library, as far as I can tell, but there are CLASS Button and TEXT definitions, etc.
I tried also to open the PATIENTS file with the following code, but I continue to get a -1 response, meaning not opened.
lFileHandle=FOPEN("c:\temp\patients.", 10)
IF lFileHandle > 0
MESSAGEBOX("Got the PATIENTS file opened", 0, "File is open")
lClosedFile=FCLOSE(lFileHandle)
IF !lClosedFile
MESSAGEBOX("File didn't close", 0, "File not closed")
ENDIF
ELSE
MESSAGEBOX("PATIENTS file didn't open", 0, "File didn't open")
ENDIF
