The file command is to easy. Is take a a string(Name of file) and the acces mode a string (r) read (w) write (rw) read/write (a) append. This two string is on the stack in order the filename and after the acces mode and the command file put your a value of file type on the stack. With this value you can make read and write for the acces mode you set.

Thanks Eric
I got the file operators syntax and tried it
but I could not understand how it works.
That is the reason I wanted examples.
What I am looking to do is to have a basic form (PS File) on a printer and
to be able to feed it variable data like addresses and names from a flat file
while pulling in graphics according to the name
Any help is appreciated
Thank You

(name.txt) (r) file %OS= file
{ %OS= file
dup 250 string readline %OS= file string bool
%if the boolean is false you take EOF
{ %If you take true %OS= file string
PosX PosY moveto %OS= file string
show %OS= file
/PosY PosY 20 sub def %OS= file
}
{ %If you take the eof %OS= file string
PosX PosY moveto %OS= file
