PASCAL: AN INTRODUCTION

INITIALISATION OF PACKED CHARACTER ARRAYS
Packed arrays of characters are initialised by equating the array to a text string enclosed by single quotes, eg,


	type  string = PACKED ARRAY [1..15] of char;
	var   message : string;

	      message := 'Good morning!  ';  {must be fifteen characters long}

MULTIDIMENSIONED ARRAYS
The following statement creates a type definition for an integer array called multi of 10 by 10 elements (100 in all). Remember that arrays are split up into row and columns. The first index is the row, the second index is the column.


	type  multi = ARRAY [1..10, 1..10] of integer;
	begin work : multi;

To print out each of the various elements of work, consider


	  for  row := 1 to 10 do
	    for  column := 1 to 10 do
	        writeln('Multi[',row,',',column,'] is ',multi[row,column];
