Solving and Integrating Programs 14–11
Restrictions on Solving and Integrating
The SOLVE variable and
³
FN d variable instructions cannot call a routine that
contains another SOLVE or
³
FN instruction. That is, neither of these instructions
can be used recursively. For example, attempting to calculate a multiple integral
will result in an
³
1
³
2
error. Also, SOLVE and
³
FN cannot call a routine that
contains an
/
label
instruction; if attempted, a
# !#
or
³

!#
error will be returned. SOLVE cannot call a routine that contains an
³
FN instruction (produces a
#1
³
2
error), just as
³
FN cannot call a
routine that contains a SOLVE instruction (produces an
³
1 #2
error).
The SOLVE
variable and
³
FN d variable instructions in a program use one of the
seven pending subroutine returns in the calculator. (Refer to "Nested Subroutines"
in chapter 13.)
The SOLVE and
³
FN operations automatically set Decimal display format.
