===== VAL ✓ =====

===== SYNTAX =====
     = VAL(string)

==== PURPOSE ====


The ''VAL'' command is a function that allows you to convert a string that represents 
a number into a integer numeric value. In other words, it takes a string that contains 
numbers and returns the corresponding numeric value.

The ''VAL'' command is very useful when working with user input, because the user 
often enters numbers as strings. For example, if we ask the user to enter their age,
the input will be a string. In order to perform calculations with this age, we must 
first convert it to a number.

The ''VAL'' function reads the string from left to right and stops at the first 
character that is not a number. The ''VAL'' function ignores spaces at the beginning 
of the string. If the string does not begin with a number or contains only 
non-numeric characters, the ''VAL'' function returns zero.



==== EXAMPLE ====
    PRINT VAL("123")
