Ok, heres my problem. I'm doing a test to see how the input/output to a file works, and i can output 2 variables, but i cant get 2 variables. Should i be able to ? If so, why isnt it working, it says "attempt to read past eof"

heres my code:
code:
var filenum, filename, iocapacity, streamin, streamout : int
var test : string
var price : real
price := 29.99
test := "item"
open : streamout, "test.txt", put
put : streamout, test, price

close : streamout

open : streamin, "test.txt", get
get : streamin, test, price

close : streamin
put test, price

when you are doing this:
code:
put : streamout, test, price
you have outputted the information on 1 line, so when you tried to get it, test now becomes "item29.99" and there isn't any info for you to get on the next line, so that gives you an error.

code:
put : streamout, test, '/n', price
doing this will output an endline character, and it skips a line in the textfile.

edit: or, as dodge suggested, you can use skip instead of '/n'.
