Hello,

Is there a calculator digraph for an upper case Delta?

Regards,

Mark

Do you mean character number 130?

\130 or \.V   (capital V)

You can always use \nnn (3-digit decimal character number),
and if there is a 2-character "digraph,"
it will appear if you convert a string containing the character
using this program (for any HP48/49/50):

\<< STD 64 STWS \->STR 3 TRANSIO RCLF SIZE 3 >
#2F34Fh #2FEC9h IFTE SYSEVAL \>> 'OUT' STO

The above program comes from:

"Ascii Import/Export for SD card and Emulator"
http://groups.google.com/group/comp.sys.hp48/msg/4e7ed90b3cf11c42

One should back up memory
before testing any program containing syseval, etc.,
because any error in the entry or execution
of programs using system functions
could cause data loss.

Thanks for the reply John! You had previously posted this list:

Num   Sym   Description
---   ---   -----------
128   \<)   angle symbol
131   \v/   square root
132   \.S   integral symbol
133   \GS   Greek Sigma (\GSLIST)
135   \pi   pi
136   \.d   derivative symbol
137   \<=3D   less or equal
138   \>=3D   greater or equal
139   \=3D/   unequal
141   \->   right arrow (\->LIST, \-> a b c)
142   \<-   left  arrow (\<-local)
143   \|v   down  arrow (\|vMATCH)
144   \|^   up    arrow (\|^MATCH)
156   \PI   capital  pi (\PILIST)
159   \oo   infinity
171   \<<   program delimiters
187   \>>
092   \\    backslash

and I was just looking for something that specifically
represented an upper case Delta. I was snooping
around on the Internet and according to one web site
I can't even produce the character in Notepad using
an Alt key code. I'll try the code you provided and
see what I come up with.

Regards,

Mark

It's so rare that I get to correct John, I'm going to throw a party on
the weekend.  Couldn't the newsgroup come up with a congratulatory T-
shirt or something?


Character 130, the del or nabla, works only as u/c delta if you turn
the calculator upside down.  The u/c delta lives at CHR 155, or
directly from alpha-RS-C.

Using your character string to "digraph" conversion
program I came up with the following:

ASCII Num (DEC)   Sym   Description
-------------------------    ------    ---------------
155                        \GD   Upper case Delta
146                        \Gd   Lower case Delta

I added them to your list.

What's the occasion?

[concerning "Translation mode 3"
for representing 8-bit characters using 7-bit common "ascii" characters,
using special "backslash" sequences, e.g. \<< a program \>> ]

A chart which I had once posted,
for programming purposes,
included only those non-ascii symbols
most commonly needed for programs and user commands.

In particular, the only Greek letters
used in commands (or functions)
are \pi, \PI and \GS (Sigma),
which were therefore the only Greek letters
included in the originally posted chart.

Other rarely used symbols which have digraphs,
but are not required for programming,
were also not included.

The only non-numeric "backslash" sequence for characters 0-127 is:
092 \ \\ (a backslash character "escapes" itself)

The following will create a table for all characters 128-255;
you will notice that some have "digraphs" and others do not:

\<< "" 128 255 FOR n
n " " +
n CHR + " " +
n CHR KVIS + @ see note below
10 CHR + +
NEXT \>>

Note: you can use either 'KVIS' or 'OUT'
(which translate 8-bit text to 7-bit text)
 from the previous post or its referenced article:

"Ascii Import/Export for SD card and Emulator"
http://groups.google.com/group/comp.sys.hp48/msg/4e7ed90b3cf11c42

The HP48 series user manuals also may have a complete chart,
as do various old pocket guides (e.g. by Jim Donnelly) for HP48.

How did you find out that I was hanging by my feet at the time,
while swinging on my trapeze?

People observing on the ground also voted for character 130,
as representing what I looked like myself at that time :)

Good catch!

I found that post:

http://groups.google.com/group/comp.sys.hp48/msg/52e9cc3ee2b369b8

And within that post is further said:

| Lower-case Greek letters are generally like \Ga (alpha); the other
| upper-case Greek letters are \GD (delta) and \GW (omega).

Voila!

-----

Meanwhile, Joe supplied the entire table as a web page, looking
much as it appears in older HP manuals and guides by Donnelly:

http://holyjoe.net/hp/tiotable.htm

That web page is, however, a composite of nine "PNG" images,
with a short page of HTML to create the visual effect of a single chart.=


Joe's chart shows the screen characters as images, using no text.

The above posting was made entirely in 7-bit text,
supplemented by verbal descriptions.

The calculator "table generator" program previously posted in this threa=
d
creates instead a single 8-bit text string, viewable on the calculator i=
tself.

Three different approaches, for three different viewing environments.

Does this cover all the bases?  What about Home Plate?
