seqn()

seqn(Expr(u, n [, ListOfInitTerms[, nMax
⇒
[, CeilingValue]]]) list
Generates a list of terms for a sequence u(n)=Expr(u, n) as follows:
Increments n from 1 through nMax by 1, evaluates u(n) for
corresponding values of n using the Expr(u, n) formula and
ListOfInitTerms, and returns the results as a list.
seqn(Expr(n [, nMax [, CeilingValue]])
Generates a list of terms for a non-recursive sequence u(n)=Expr(n)
as follows: Increments n from 1 through nMax by 1, evaluates u(n)
for corresponding values of n using the Expr(n) formula, and returns
the results as a list.
If nMax is missing, nMax is set to 2500
If nMax=0, nMax is set to 2500
Note: seqn() calls seqGen( ) with n0=1 and nstep =1

setMode()

modeNameInteger
setMode(
⇒
list integer list
setMode( )
Valid only within a function or program.
modeNameInteger
setMode(
mode modeNameInteger to the new setting settingInteger, and
returns an integer corresponding to the original setting of that
mode. The change is limited to the duration of the program/
function's execution.
modeNameInteger specifies which mode you want to set. It must
be one of the mode integers from the table below.
settingInteger specifies the new setting for the mode. It must be
one of the setting integers listed below for the specific mode you
are setting.
setMode(list) lets you change multiple settings. list contains
pairs of mode integers and setting integers. setMode(list)
returns a similar list whose integer pairs represent the original
modes and settings.
If you have saved all mode settings with getMode(0)
you can use setMode(var) to restore those settings until the
function or program exits. See getMode(), page 42.
The current mode settings are passed to called
Note:
subroutines. If any subroutine changes a mode setting, the mode
change will be lost when control returns to the calling routine.
