DSE
Decrement and skip if equal or less. „DSE nn" operates on data register nn
and depending on the test skips or executes the next program line. The data
register must initially be loaded with a value of the form ccccc.tttdd where
ccccc is the current counter value, ttt is the test value and dd is the decrement
value (increment value for the ISG command).
The DSE command will substract dd from ccccc and compare the result to ttt.
If the result is less than or equal to ttt the next program line will be skipped.
See RCL for indirect addressing modes
END
Ends a program and separates multiple „global" prorgams. A global program
can contain multiple „local" subprograms which end with RTN
ENG
Select engineering display format rounded to n+1 valid digits where the
exponent is always a multiple of 3 and the mantissa is ≥1. This does not affect
the internal representation of the number.
See RCL for indirect addressing modes
Push the stack
ENTER↑
Exponential function base e
E↑X
E↑X-1
Calculate (e↑x) – 1, used for very small values of X
FACT
Faculty von X (X!). Does not allow for negative or non-integer values.
FC?
Check whether flag nn is clear. See CF
PRGM mode: If the condition is true the next program step is executed,
otherwise it is skipped.
RUN mode: The test result is displayed (YES or NO)
FC?C
Check whether flag nn is clear and then clear it. See CF
FIX
Select fix point display format rounded to n valid digits after the decimal point.
Will automatically switch to SCI format if the number gets too big or too small.
This does not affect the internal representation of the number.
See RCL for indirect addressing modes
FRC
Fractional part of X
FS?
Check whether flag nn is set. See CF
FS?C
Check whether flag nn is set and then clear. See CF
GRAD
Set trigonometry mode „grad" (400)
GTO
Go to a label or program line number. Does never execute any program
instructions! See RCL for indirect addressing modes.
RUN mode:
„GTO nn" goes to the local label 00 – 99 of the current program
„GTO ALPHA <character> ALPHA" goes to the given local label of the current
program
„GTO ALPHA <name> ALPHA" goes to the given global label. „name" may
have up to 7 characters
PRGM mode:
„GTO nn" inserts a jump instruction to the given local label 00 - 99
„GTO ALPHA <character> ALPHA" inserts a jump instruction to the given
local label
„GTO ALPHA <name> ALPHA" inserts a jump instruction to the given global
label. „name" may have up to 7 characters
PRGM and RUN mode:
„GTO . nnn" goes to the program line number nnn of the current program
„GTO . EEX nnn" goes to the program line number 1nnn of the current
program (for program with more than 1000 lines)
„GTO . ALPHA <character/name> ALPHA" goes to the specified local or
HP-41CV
