Calling consecutive variables into Maple from MapleTA

[mschneider]

I have some variables in MapleTA incrementally named:

----------------The below can be copied into MapleTA---------------

$numOFdefinedANSWERS=3;
$Answer1=4;
$Answer2=7;
$Answer3=15;
#etc....  this list can go on to an undetermined length, dependent on the person building the question (if more answers are added then the user will increment numOFdefinedANSWERS accordinginly)
#From here I am hoping to build a Maple call-out that will build an array of these MapleTA variables.  At this point I am simply hoping to attain the last variable in the loop, from there I will build the array.

$maplecall=maple("
restart:
for i from 1 to $numOFdefinedANSWERS do
a:=$Answer||i
end do;
");

#Presently this call out seems to completely ignore the dollar sign...  as "Answer3" is sent back to MapleTA, when I would like "15" sent back to TA.

#I tried to modify using this callout...

$MAPLE_call=maple("
restart;
with(StringTools);
for i from 1 to $numOFdefinedANSWERS do
a:=cat(Char(36),Answer,i)
end do;
");

# This Generates a string sent back to MapleTA, that a parse seems to not handle well either?

#Any ideas are appreciated?

I'm not sure if this is acceptable in your implementation, but moving the variables inside the Maple call works. The reason is that (unfortunately) the dollar sign has a different meaning in Maple.

$MAPLE_call=maple("
Answer1:=4;
Answer2:=7;
Answer3:=15;
C:=Array([]):
for i from 1 to $numOFdefinedANSWERS do
a:=parse(cat(Answer,i)):
C:=ArrayTools[Append](C,a):
end do;
C;
");

Thank-you for the response.  I am not wanting to call the variables into Maple until desired (in other words not all together at the start).

The reasoning is User A might only have 3 defined answers to the particular question while user B might have 7 defined answers.  I was hoping the for loop would gradually gather all the answers rather than having them defined at the start of the call to maple.
