This function is defined in routine F:
F01 LBL F
F02 RCL D
F03 RCL- M
F04 RCL* S
F05 X*
F06 2
F07 *
F08 +•-
F09 e*
F10 RTN
Other routines prompt for the known values and do the other calcula
tions to find Q(D), the upper-tail area of a normal curve. The
integration itself is set up and executed from routine Q:
Q01 LBL Q
Q02 RCL M Recalls the lower limit of integration.
Q03 RCL X Recalls the upper limit of integration. (X =
D.)
Q04 FN= F Specifies the function defined by LBL F for
integration.
Q05 /FN d D Integrates the normal function for the vari-
• able D.
Limitations. The /FN variable instruction cannot call a routine that
contains another /FN instruction; that is, it cannot be used recursively,
so you cannot calculate multiple integrals (X<XFN> error). Nor can
/FN call a routine that contains a FN= label instruction (JFN
ACTIVE error). /FN cannot call a routine that contains a SOLVE in
struction (S(SOLVE) error), just as SOLVE cannot call a routine that
contains an integration instruction (SOLVE<JTN> error).
The JTN d variable instruction in a program uses one of the seven
pending subroutine returns in the calculator. (Refer to *Nested Sub
routines* in chapter 6.)
