@Joe Riel 

Okay thanks for pointing that out. 

Great! thanks.  I also found out this works.

changedir:=proc(change)
  if _params['change']=NULL then currentdir("f:/") else currentdir(change) end if:
end proc:

Now in this particular case I need to enter quotes changedir("c:/test") How can I get it to work so that I can just enter the pathname without the quotes, like changedir(c:/test) ?

Okay thanks.  table() yes, and not rtable. 

The only alternative I could could think of was to use a variable as a counter in my loop, which created my table.  And then just call the variable.

Great post!  The lack of voting can be attributed to being burried on the new primes site.  Had this post never appeared up front I never would have read about it unless it appeared in a search call. 

It's almost impossible to scroll through the posts as easily as the old mapleprimes.  Too much summary information displayed to comfortably scroll through on the second level.  Rarely can I enjoy comfortably scanning the titles of posts in a category without getting overloaded with all the extra summaries displayed.  There appears to be a maximum of 3 levels here on new mapleprimes not that it's bad, I just don't agree with the way the 2nd level is layed out. 

I believe there was a push to have summary info displayed but no one has complained so everyone must be happy with it.  I however don't think it works well.  Second level display should display the same as the first.

Administrator note - please branch, much info here changes topic.  (at least one thing I do agree with is the branching)

Overlay a peak at 9 months from each holiday. 

It's actually odd that there isn't a spike in Valentines babies (9months from valentines day) at least I would have expected a spike in mid November well maybe not, but the data shows that it's almost the lowest relative point, ... let's think for a moment ... hmm..., okay probably too many heartbreaks I guess and people looking for new love, not really a time to think about having kids right off the bat, maybe these are oops babies.  You'll also notice a spike 1 month afterwards before it drops again, there is no holidays there... oh!  maybe the march break!  That makes sense then.  The only other thing I was surmising about that is that women on the pill go off after Valentines day and so when there next monthly cycle begins ... hence the 1 month spike.  However that's just my speculation.  Also interesting, is that there is quite a spike for Christmas and newyears, September babies (9 months from Christmas or newyears), people ringing in the new year, it's quite a celebration time.  Also Canada day or independence day babies there is another spike.

I will show you exactly what I see using Maple 12 on a freshly opened document. 

command                          memory displayed

Newly opened document       0.43M

restart; a:=7; gc();              0.81M
restart;                               0.81M
gc();                                  1.49M
restart; gc();                       0.43M
gc();                                   1.49M

Note: The 1.49M seems to vary from 1.37 to 1.49 sometimes

What I see is that if I use restart; and gc() on a seperate lines the memory used is higher than if I use
restart; gc; on the same line.  Perhaps this is a glitch for me since no one else appears to observe the same thing. 

I was able to check this evening that the issue exists in Maple 14 as well.  Granted 1/2 a megabyte is nothing, but shouldn't the same operations regardless of wether they occur on seperate lines or not result in the same value (The memory I'm talking about is the value displayed in the bottom right corner of Maple).

(hirnyk:All those pictures could be created with maple.) - This sounds like a challenge.  Sure, why not?  I would like to see it done too :)

So why mathematica?  I'm guessing he was introduced to mathematica before maple.  University professors tend to stick to one CAS, I'm also guessing that the University purchases mathematica liscenses and not Maple.

Another possibility is mathematica was built on graphics 1st functionality 2nd.  Maple's abilities in graphics are good, I just find Maple requires a little more work, they were quite poor in the beginning but catching up quickly now.  I'm guessing the author found mathematica a little easier to work with the graphics manipulations.

Thanks, I actually tried something similar to that

with(StringTools):
g:=cat("c:/test"||FormatTime("%B%d%H%M")||".txt")
writedata(g,test)

As you can see I forgot the comma seperators among other things I should have realized.

Currently I'm getting these errors

    Error, index out of bounds
                                                                 true
                                                                 k:=1
    Error, Array index out of range
    Error, inverted range in Array index
                                                                  100
    Error, (in readbytes) JPEG Error: Not a JPEG file: starts with 0x48 0x54
    Error, (in ImageTools:-View) parameters must be images or lists of images

Is it supposed to work with Maple 12 ?

Thanks, I believe the spreadsheet option should work for what I'm thinking of using it for. 

However I would have liked to have had a simple table representation automatically set up using code on the document page.  Perhaps this functionality will be added in an update or a newer version?
