That IS a bit odd, I put it into my compiler, putting in proper indents, so it looked like this:

Код:

stock fdeleteline(filename[], line[])
{
    if(fexist(filename)){
        new temp[256];
	new File:fhandle = fopen(filename,io_read);
	fread(fhandle,temp,sizeof(temp),false);
	if(strfind(temp,line,true)==-1){return 0;}
	else{
	    fclose(fhandle);
	    fremove(filename);
	    for(new i=0;i<strlen(temp);i++){
	        new templine[256];
		strmid(templine,temp,i,i+strlen(line));
		if(strcmp(templine,line,true)){
		    strdel(temp,i,i+strlen(line));
		    fcreate(filename);
		    fhandle = fopen(filename,io_write);
		    fwrite(fhandle,temp);
		    fclose(fhandle);
		    return 1;
		}
	    }
	}
    }
}

And it compiled without any errors for me. Try that indented version, and see what happens, perhaps?
