i was trying out some program and it got compiled without any error, but when i was running the program there was an error " CAN'T CREAT C:\TC\BIN\TCDEF.DPR ", then i press enter and the programs run fine, but i do not understand what is this TCDEF.DPR file and what does it do.

I am facing a new problem now,
the C compilwer is compiling the prgran properly, but while running it give a linker error: Unable to open file TCDEF.EXE.
do u think i need to get a new compiler.
this gave me problem before also, i reinstalled TC and after running a couple of programs it is giving trpuble again.

Hope to hear from u soon.
