Derived Parameter Submenu

Functions in Derive New Parameter Dialog and Their Definitions:

sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, exp, ln, log, abs, sqrt, neg:

for the above functions, the syntax for FSC-H parameter would be
FXN(FSC-H) where FXN is replaced with one of the strings above.

rand(x):

rand() is the same as rand(1), generates random number from 0 to x

if(a,b,c):

evaluate "a": if true, then return "b" else "c"

max, max, sd, cv:

FXN(a,b,c,...) returns the function value on all parameters

norm(a,b):

random number (normal distribution) with mean = a and sd = b

sub(s,a,b):

substring of s, starting at a and length b characters

find(s,a[,i]):

returns the character position of "a" in "s", start searching at i
(first char = 1; 0 = no occurence)

char(n):

returns a string equivalent of numeric value n

num(s):

converts the string s to a number

word(s,i,d):

finds word #i in s, delimited by "d"

repl(s,a,b):

replace all occurrences of "a" in "s" with "b"

rep1(s,a,b):

replace first occurrence of "a" in "s" with "b"

len(s):

length of s

del(s,o,j):

delete j characters in s starting at i

ins(s,a,i):

insert string a into s at position i

start, end, contains (a,b):

1 if a starts/ends/contains string b

uppercase/lowercase(a):

returns upper/lower (a)

truncate(a, i):

truncate a to i chars (if i < 0, trim last -i chars from end)

var(v, n):

define variable v, give value n

for(Ei, Eq, Et, El, Er):

Ei = initial expression; Eq = loop qualifier (must be numeric); El = loop;
Et = loop terminal statement; Er = fxn result

Execution:

Ei, then test Eq:
if true, then (El and then Et and repeat test) else Er
for (var(c,1); var(x,0), x < 3, var(x, x+1), var(c, c*2), c) ... returns 4
HardExits afer 1,000 loops UNLESS the variable "MaxLoops" is defined
