C129 error in keil C

[sahilt]

hey guys..i am currently working on a program on keil and i am not able to compile it coz everytime i try, i gives me an error C129: missing ';' before '\'. Can anyone plz help me? The program is as follows:

Try:

a) posting it again without the formatting
b) telling us on which line it reports the error.

 

[sahilt]

okk...thanks steve..,i'll do that...but its just reporting the error C129 on the very first line that is:

rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\ f0\fnil\fcharset0 Calibri;}

and i have no idea why this is happening... as i mentioned in my first post: C128 missing ';' before '\'
Some help would be appreciated. Thanks in advance!!

 

[(*steve*)]

on the very first line that is:

rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\ f0\fnil\fcharset0 Calibri;}

I'm pretty sure your first line doesn't look like that.

Perhaps you should try a plain ascii file, not what appears to be rtf.

Using a PC? Copy and paste it into notepad.

 

[sahilt]

oh!! ok...sorry if i did something wrong...i am simply copying and pasting my program in keil into the notepad. And when i try to look for the error ..all it points to is the very first line....dats wat i don't understand..

Delete these 2 lines and try again:

umm..i don't think so steve..but still as you suggested,i tried doing so and after compiling the program..it gave many more errors like:

so when i again included the lines, it gave back the same error..
TRANS1.C(1): error C129: missing ';' before '\'

Well, maybe there is something in those first 2 lines that are your actual code. I can't tell.

Presumably you know what the code should look like, and presumably that alphabet soup isn't all part of it.

But it is certainly true that P1, P2, etc do not appear to be defined.

And what is interesting is that you assign values to them in code even though your gobal variables seem to have initial values based on their (undefined) values.

I think these errors are real.

 

[sahilt]

so...wat exactly do you mean by these errors are real..??
And is there anyway you could suggest on how I could solve my problem??

 

[(*steve*)]

The errors appear real because now the code appears wrong.

Define P1 and P2 (etc) and some of your errors will go away.

Then work on the rest.

Perhaps one of those commented out includes contains the definitions. Why do you have them commented out?
