Abstract
All identifiers used in a Pascal program must be defined or declared at the beginning of the BLOCK. The order of definition/declaration (L,C,T,V,S) is very important; syntax diagrams for these are given in Appendix A. All identifiers used in a program must be declared. The const definition is used for parameters that do not change their value throughout the execution of the program. The var declaration can be any one of the data type: real,integer, boolean or char (short for character). In addition to these four simple types of variables, Pascal allows more complex variable types known as ‘structured’ data types. These include array record, set and file and are described in Chapter 6.
