Assignment Statement

∟Assignment Statement

This section describes what is an assignment statement in H language.

An assignment statement is a statement that assigns data objects to variables or reference holders with the following syntax:

variable = object;
array[i] = object;
hash[name] = object;

Examples of assignment statements are:

s = "Hello"; # assigns a string object to a variable

a = array(); # assigns an array object to a variable
a[0] <- "Hello"; # assigns a string object to reference holder

h = hash(); # assigns a hash object to a variable
h["message"] <- "Hello"; # assigns a string object to reference holder

The equal sign "=" is actually an alias of the keyword $refers. So assignment statements actually have the follow syntax:

variable $refers object;
array[i] $refers object;
hash[name] $refers object;

Design options:

1. Use the equal sign "=" to identify an assignment statement:

x = 1;

2. Use "<-" to identify an assignment statement:

x <- 1;
