Icon program task

Implement a subset of Icon and write a test program in Icon which will accept text as input and produce an alphabetical list of words in the text with a count of the frequency of each word.

## Deliverables

Icon is a string processing language based on an older language Snobol.

A string value is assigned to a variable by an assignment statement.

mystring := "next hour buy flour for our cake"

The generator "find" returns a sequence of integers giving the position of the first character in which a matching substring occurs.

example

mystring := "next hour buy flour for our cake"

n := find("our",mystring)

write(n)

output

7

example

mystring := "next hour buy flour for our cake"

every n:= find("our",mystring) do write(n)

output

7

17

25

example

mystring := "next hour buy flour for our cake"

if find("our",mystring) then write("yes") else write("no")

output

yes

example

mystring := "next hour buy flour for our cake"

if find("your",mystring) then write("yes") else write("no")

output

no

Implement a subset of Icon including read, write, find, every, the integer operators +, -, *, and /, and the relational operators =, <, and <=.

Write a test program in Icon which will accept text as input and produce an alphabetical list of words in the text with a count of the frequency of each word.
