redirected output has extra cr

write one line program

print "x"

call it z.bas
compile it with freebasic
run it like this z > z.txt

if you look at z.txt with a binary editor, you see x cr cr lf
if you compile it with qb45 you see x cr lf

freebasic seems to be adding an extra cr during redirection

dir attributes

dim as string t t = dir("*",16) do if t = "" then exit do print t t = dir() loop This code returns everything, not just directory names. There appears to be a discrepancy in the docs for DIR. One place it says the directory attribute is 0x8 and another place 0x10.

I was able to use regular strings by allocating len(text) + 12 bytes for the descriptor which is the value of sizeof(string).

yes, that is what i thought. once you close piped stdin, it does not seem to get reopened for keyboard input.

i was unsure if it was a compiler issue or a "feature" of dos pipes.

the program would be run like this

dir | example.exe

the example code i posted earlier processes chars from dir via the pipe then hangs at inkey. i have to close the dos box with the X button.

i'm writing an editor which first reads a file from disk, then receives commands from the keyboard. i thought it would be handy to be able to read the file from stdin instead of disk. this works, but the console remains pointed at the piped input so i am unable to receive editor commands from the ke...

life after piping to stdin

open cons for input as #1
do while not eof(1)
line input #1, x
print x
loop
close #1

x = inkey

x never sees any chars in the last line.

is there any cure for this?

i might have figured it out ... i was exiting with SYSTEM. i changed that to END, compiled with -profile, ran the program, and got a file called PROFILE.TXT.

profile ... where is gmon.out

I compiled my program with the -profile switch. The exe gets bigger and slower, but I cannot find gmon.out!

poking screen of dos box

i am translating a program from qb45 to freebasic that uses poke to change screen colors thusly

def seg = &hb800
poke 1,&h2e

i expected to be able to translate that into

poke &hb8001,&h2e

but it does not work.

i am working in a dos box (console) of windows xp.

trapping control c and control break

i'm writing a program that should not allow control-c or control-break but it might be handy to trap rather than suppress them. is there any way to do that without 'on error' ?

general protection fault

ok i figured out how to operate the debugger the program does not fail every time when it does fail, it is at a line like this ... type cell as string ptr value as cell ptr prevcell as cell ptr nextcell end type ... btm = callocate(len(cell)) btm->value = callocate(3) *btm->value= "btm"
