Could any one tell me how to indirect files when in turbo C integrated environment. Setting Command line to " < filename"does not help. I used Instant-C also earlier and could not find a way to use indirection. Thanks

Setting Command line to " < filename"does not help. > Within the Integrated Environment you can't via the Args option. But, you could alway modify your program to look for args passed or include the < filename on the command line (ie. tc sample.c <filename). This will pass filename to stdin. If you don't believe it, try the following: 1. enter this program in via your editor. (call it sample.c) #include <stdio.h> main() { char buffer[128]; int numchars; while ((numchars = read(fileno(stdin), buffer, 128)) > 0) write(fileno(stdout), buffer, numchars); } 2. go into TurboC with the following command line. tc sample.c <sample.c 3. you will notice that the file sample.c is displayed on the screen and Turbo C is waiting for you to press any key. NOTE: This only works once. You will have to exit and retype the command line to do it again. This is because the redirected file is not re-opened each time you run the program and TurboC didn't open it to start with, Command.com did. -- Mark Gorlinsky - AMD Processor Products Division/APPS SQA UUCP: {decwrl,ihnp4,allegra}!amd!markg AT&T: (408) 982-7811 DISCLAIMER: My opinions are mine, not my employers.

This seems like a more reasonable explanation, particularly since BORLAND is not noted for using stdin for getting keyboard characters and instead using INT 9 (I think that's the keyboard, but I am too lazy to look it up). > > 3. you will notice that the file sample.c is displayed on the screen and > Turbo C is waiting for you to press any key. > > NOTE: This only works once.

This is the same thing that Wordstar will do if a file name is mentioned on the command line. Bob Leder

Sorry you misunderstood. The sample.c program will read stdin, tc will not. That's why it worked. Try using a different file for the indirection. You will see that that file will be displayed and not sample.c. >> >> 3. you will notice that the file sample.c is displayed on the screen and >> Turbo C is waiting for you to press any key. >> >> NOTE: This only works once.

Can anyone go in depth to Turbo C's relation with dos. Like will it open a file that is given as a full path name?, redirection, pipes, macros, etc ...
