A variety of things, most commonly a recursive call to a function or procedure that does not end.

What is "ord"? Do you mean the ord function? Or perhaps you mean "record"?

Could you post your code?

I think it was supposed to be "search a word".
Also, the overflow is caused by trying to use too many variables within procedures. The program can not longer allocate memory for the procedures variables when the procedure is called. As Actor said, it is very common with recursive functions, especially if the recursive functions have variable declarations.
It could also be only 2 or 3 variables, if they are each 40 Kbytes as TP7 only allows 64K total.
