• 1. Labeling longitudes and latitudes
Hi, Does anyone know if there is a command to add longitude and latitude labels in the WorldPlot package? I'd like to use those labels to designate the parallels and meridians, e.g., -180, -165,.... I asked this question last year with no response, but maybe with Mathematica 6, this is easier.... Thanks! Kevin
• 2. hypergeom
Hi, I got this function HypergeometricPFQ[{1}, {1/2 + k/2, 1 + k/2}, -1/4 t^2 w^2] How can I write it in normal mathematical equation? Mathematica help says this: HypergeometricPFQ[{a1, a2....ap},{b1, b2 ....bq},z] is the generalized hypergeometric function pFq(a;b;z) I don't get what is p and q in my case? Kindly help..
• 3. Can an arrow be drawn on a 3D plot?
The code below draws a surface and a contour over that surface. I'd like to show the direction of the contour with arrows. Looks like Arrow only works in 2D. Any way to draw an arrow lying on a 3-D surface? Ideally, I'd like to place say 2 arrows on the green contour on the red surface showing the direction (of integration). f[z_] := z; iSurface = ParametricPlot3D[ {Re[z], Im[z], Im[f[z]]} /. z -> r*Exp[I*t], {r, 0, 5}, {t, -Pi, Pi}, PlotStyle -> Red]; traceC1 = ParametricPlot3D[ {Re[z], Im[z], Im[f[z]]} /. z -> 2*Exp[I*t], {t, 0, 2*Pi}, PlotStyle -> {Darker[Green], Thickness[0.004]}]; Show[{iSurface, traceC1}, PlotRange -> {{-7, 7}, {-7, 7}, {-7, 7}}, BoxRatios -> {1, 1, 1}, ImageSize -> {500, 500}]
• 4. step into dsolve routine on step at a time
Hello group. Long time ago, I remember seeing an "option" or a function that allows one to see what DSolve is doing step by step. I just don't recall what it was. I searched everywhere for it and can't find it. Does anyone know what I'm talking about? It basically shows what DSolve does except step by step. I just don't recall if it was an external function written by someone or an option inside the DSolve. Thanks for any info in advance. Sean

```In article <bfgauh\$8bi\$ XXXX@XXXXX.COM >,

I can tell you for sure that the second one has not been fixed. The only
solution is to set the notebook magnification at 100%. It is incredibly
annoying.

### Re: Re: v5 for Mac

```The first of these --- the (not) rotated text bug --- has not been
fixed either.

Another bizarre bug has popped up in 5.0: In text cells, lines are
sometimes broken after apostrophes. So a word like
can\[CloseCurlyQuote]t will break between \[CloseCurlyQuote] and t.
Astonishing. I wonder if that happens in Windows too.

```Selwyn,

The CloseCurlyQuote bug does sometimes happen in Windows98.

### Re: Re: Re: v5 for Mac

```I've come to a standstill with v 5 on OS X (10.2.6).  After months of
back-and-forth with Wolfram support, they have declared it a personal
problem.  (Can't duplicate but won't tell me what machines they tested
it on.)

Apparently the problem is machine dependent-- it happens with 100%
reliability on our fast dual processor machines, but not on our
laptops. To see the problem (or not), put a series of expressions of
the form (multiple expressions accelerates the crash) into a cell and
evaluate:

ExportString["a","GIF"];
ExportString["a","GIF"];
. . . .

Also crashes Mathematica with other image formats.  I would appreciate
hearing how others fare with this (esp. w.r.t. machine).  Wolfram support
accuses me (literally!!) of having an impure system.  Impure thoughts
maybe, but I replicated this on a machine right out of its carton, with
-only- Mathematica installed.  (Hmm, maybe they meant Mathematica....)

I'm sorry for sending what amounts to a bug report to the list, but
I went through channels with no joy.  Unfortunately, this feature is
important to a series of my applications, hence my frustration.

A few other notes: -  Even if this fails to crash Mathematica (on a PB
for example), it's an order of magnitude (!!) slower than 4.2

- Under Panther, any export call of this type is DOA (dead stall), whatever the machine.

- Nothing like this happens under v 4.2 (even under Panther), but
it is apparent from my observations that Mathematica's converter,
gif.exe/pnm.exe, has a memory leak.  The converters (4.2) are unusably
slow under Panther.

### Re: Re: v5 for Mac

```Here's the fix for the CloseCurlyQuote "bug" (thanks to tech support):

============
``In SystemFiles/FrontEnd/TextResources/UnicodeCharacters.tr, look for
the
entries for 2018 and 2019.  They are, presently...

0x2018 \[OpenCurlyQuote] (\$['\$	 \$‘\$) Open -10 None 0
0 0x2019
0x2019 \[CloseCurlyQuote] (\$]'\$   \$’\$) Close -10 None
0 0

Change them to...

0x2018 \[OpenCurlyQuote] (\$['\$	 \$‘\$) Letter
0x2019 \[CloseCurlyQuote] (\$]'\$   \$’\$) Letter

Now delete caches and restart. ''
===============

(Note: I've noticed--since 5.0--that editing .tr files with Mathematica
ruins them, because they're turned into notebooks. Twice now I've had
to restore a .tr file from the CD, and then do the editing with a text
editor.)
