Restrictions on Solving and Integrating
The SOLVE variable and
∫
FN d variable instructions cannot call a routine that
contains another SOLVE or
∫
FN instruction. That is, neither of these instructions
can be used recursively. For example, attempting to calculate a multiple integral
will result in an
∫

∫

error. Also, SOLVE and
∫
FN cannot call a routine that
contains an

label instruction; if attempted, a
 
or
∫


error will be returned. SOLVE cannot call a routine that contains an
∫
FN instruction (produces a

∫

error), just as
∫
FN cannot call a routine that contains a SOLVE
instruction (produces an
∫

error).
The SOLVE variable and
∫
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
∫
FN operations automatically set Decimal display format.
