Question:Error, too many levels of recursion

In Maple V, Release 4 (1996):

 

T:=table():
i:=1:N:=5000;

for i from i to N  
do
   T[i]:=T[i+1]:
   T[i+1]:=1;
   eval(T[1]);
od:
print(i);

for i from i to N  
do
   T[i]:=T[i+1]:
   T[i+1]:=1;
   eval(T[1]);
od:
print(i);

I receive this output:

N := 5000
Error, too many levels of recursion
3607
5001

Can You explain this occurence, as well as the following one:

In Maple V, Release 4 (1996):

 

T:=table():
i:=1:N:=5000;

for i from i to N  
do
  T[i]:=T[i+1]:
  eval(T[1]);
od:
print(i);
 
for i from i to N  
do
  T[i]:=T[i+1]:
  eval(T[1]);
od:
print(i);;

gives:

N := 5000
Error, too many levels of recursion
3607
Error, too many levels of recursion
3607

How does one control allowance for recursion depth?
