Instructions of a high level language are coded in many statements. At the time of their execution, they are converted statement by statement into machine code using system software, called Interpreters. For example, programs written in BASIC language are executed using Advanced BASIC (BASICA) or GWBASIC interpreters. ere are certain disadvantages of interpreters. As instructions are translated and executed simultaneously using interpreters, they are very slow for executing large programs. Hence, interpreters are not suitable for most of the applications development.
