Purpose of Assignment:
Intended purpose of this assignment is to give students an exercise that can facilitate them
while working in any professional software development environments. After attempting
this assignment students will be able to:
 Familiarize with the core concepts of a special purpose programming language
‘SNOBOL’ which is used for string manipulation and handling.
 Learn language basic syntax.

 Students will get comprehensive understanding of important concepts of

Scenario:
IdevSpot- String Manipulation Library
IdevSpot wants to develop a stand alone library application named IdevSpot- String
Manipulation Library. It adds a set of general purpose functions to the scripting
languages. The main features are as follow:
 Significantly simplified string manipulation
 High performance interoperability with other source/libraries
 Improved overall performance of common string operations
Evaluation:
IdevSpot-Software Development team has decided to use SNOBOL language to develop
this library. Now being a part of this project answer the following questions:
A. The project team faces some issues while developing this library. According to
you what can be the reasons for these issues? [5] B. Write the value of OUTPUT variable: [10]
a. OUTPUT = 3 * (12 + 3)
b. OUTPUT = 10 / 2 * 5
c. OUTPUT = 24 / 4 / 2
d. OUTPUT = 2 ** (2 ** 4)
e. OUTPUT = 14 + ' 54'
f. OUTPUT = 'ONE,' 'TWO,' 'THREE'
g. OUTPUT = (20 - 17) ' DOG NIGHT'
h. OUTPUT = 19 (12 / 3)
i. ABC = 'EGG'
D = 'SHELL'
N1 = 43
D = 17
OUTPUT = N1 + D
OUTPUT = ABC D
j. A = „PUT‟
B = 6
OUTPUT=„OUTPUT655‟ A B
C. Write a simple SNOBOL statement that replace monkey with tiger and then
remove all tigers‟ words from the given paragraph. [5]
“A monkey is in a room. Suspended from the ceiling is a bunch of bananas, beyond the
monkey's reach. However, in the room there are also a chair and a stick. The ceiling is
just the right height so that a monkey standing on a chair could knock the bananas down
with the stick.”
