   Why is PL/I a good programming language?

   • PL/I has several features that make it ideal for applications programming. One of these features is its capability for condition processing. In most languages, the program cannot recover from run-time error conditions, such as an invalid data conversion control reverts to the operating system.

   What is PL/I syntax?

   • PL/I syntax borrowed from both COBOL and Fortran syntax. So instead of noticing features that would make their job easier, Fortran programmers of the time noticed COBOL syntax and had the opinion that it was a business language, while COBOL programmers noticed Fortran syntax and looked upon it as a scientific language.

   PL/I is a block-structured language, consisting of packages, procedures, statements, expressions, and built-in functions, as shown in Figure 1. PL/I programs are made up of blocks. A block can be either a subroutine, or just a group of statements. A PL/I block allows you to produce highly modular applications, because blocks can contain ...
