variable
The
programmed
∫
FN instruction does not produce a labeled display (
∫
= value)
since this might not be the significant output for your program (that is, you might
want to do further calculations with this number before displaying it). If you
do
want this result displayed, add a PSE (
º ¤
) or STOP (
¥
) instruction to
display the result in the X–register after the
∫
FN instruction.
If the program contains a VIEW or STOP instruction, or a message for display (an
equation with Flag 10 set), then the instruction is normally executed only once — it
is not executed each time the program is called by
∫
FN. However, if VIEW or a
message is followed by PSE, then the value or message will be displayed for one
second each time the program is called. (STOP followed by PSE is ignored.)
