2 Applesoft BASIC questions/1 Hyper C question

[smmcafee@phy.mtu.edu (Sean M. McAfee)]

Criminy, I hope someone can help me.  I'm at my wit's end.

Last month, as graduation approached, I faced the impending deactivation of
my account.  I had a few large files of saved Usenet articles, and I didn't
have the time to go through them and select which ones I wanted to keep.  So,
I chopped the largest file up with "split", downloaded all the pieces to my
GS, and combined them with GSHK.

Recently, I un-shrunk the first of the pieces, and found that, somehow, all
of the carriage returns (control-M's) in the file had been turned into
control-J's.  How to reverse the change?  Since I don't (yet) have any kind
of programming shell, and since none of the text editors I have can replace
text with a control-M, I tried Applesoft BASIC first:

 5  ONERR  GOTO 100
 10 D$ =  CHR$ (4)
 20  PRINT D$;"OPEN XAA"
 30  PRINT D$;"READ XAA"
 40  PRINT D$;"OPEN XAA2"
 50  PRINT D$;"WRITE XAA2"
 60  GET A$
 70  IF A$ =  CHR$ (10) THEN  PRINT : GOTO 60
 80  PRINT A$;
 90  GOTO 60
 100  PRINT D$;"CLOSE"
 110  END 

The program didn't work, and subsequent fiddling showed that the second OPEN
seemed to cancel the first one.  Why did it do this?  I checked my copy of
"The ProDOS Handbook" by Rice and Rice, and it says:  "Under ProDOS a program
can have up to eight files open at the same time...ProDOS automatically assigns
a 1024-byte buffer to each standard file when it is opened."  So what the
#$^&*# am I doing wrong?

So then, I figured "Hey, maybe I can just load the file directly into memory
and make the control-J replacements with PEEKs and POKEs."  But when I
typed "BLOAD XAA,A$2000,TTXT" I got "NO BUFFERS AVAILABLE".  I even tried
rebooting the disk and making this the first command I entered upon starting
BASIC, but to no different effect.  How can I be out of memory before even
doing anything?

Finally, I remembered Hyper C.  I was stopped short before getting anywhere,
though, since I couldn't get the most rudimentary file I/O to work.  Can
anyone familiar with Hyper C tell me what's wrong with the following program,
which doesn't do a damn thing?

#include <std.h>

main()
{
    FILE *a;
    int i;

    create(a,"THISFILE",0);
    fprintf(a,"Hello world!\n");
}

I later tried putting the create() inside a printf() to see the return value,
which turned out to be -1; according to the documentation, this means that the
file was created successfully.  After executing the program, though, no new
file was to be found.  Help!


A quick blast from the past:  I was watching Monday's episode of "Automan" on
the Sci-Fi Channel, during which the following exchange took place between
Automan and his creator, Walter Nebuchar:

	Automan:  "When someone asks me what my sign is, what do I tell them?"
	Walter:   "...Tell them you're an Apple 2."
