Description
Conditionally executes the following command, depending on the value of an expression. The condition is run through a math calculator. If the result is zero, the command is skipped; otherwise it is executed. Command blocks may be used, which begin with a { and end with a }, and is treated by control statements such as if it were a single command (i.e. executed or skipped as a whole).
When using characters which have special meaning in LavishScript commands, such as < | and >, enclose the statement in quotes (see Syntax).
if "2 > 1"
Examples
if x == 5
{
if y == 6
varset z 17
