Syntax Description

list(expression arg1,

expression arg2, ...)

Use this function as a container to hold a group of similar expressions. The expressions must all be of the same type--either

numeric or string. If you create a list of strings, you must make sure that no string element contains a comma, since the comma is

used to delimit the list. A variable defined as a "list" can be used as an argument for the "choose" function.

EXAMPLE

fruitList = list("apple", "pear", "peach", "tangerine")

whichFruit = rand(4)

fruit = choose(whichFruit, fruitList)

weightList = list(110, 142, 153, 180, 212)

whichWeight = rand(5)

weight = choose(whichWeight, weightList)

double ln(double x)

Calculates the natural log of the argument, x. Arguments to the function must be greater than zero.

double log(double x)

double log10(double x)

double logb(double x,

string ltrim(string x)

Trims spaces from the left side of the string argument, x.
