B4P Reference

Introduction

Variable are expressions which must refer directly to a variable. Any other forms of expressions such as constants, calculations, function calls, table references, etc, are forbidden and assert exceptions. However, variable members (in structures and __arrays_ are allowed). dim(), structure(), array() and protect() are common functions which utilize this variant of code pieces.

       var 1[] = my array;

       var 2[] = 'my array[]';



          array(  var 0[],   {hog, bat, pig} );

       // array(  var 1[][], {dog, cat, rat} );   // This one is wrong

          array( :var 2[],   {dog, cat, rat} );   // This one is OK

       

       echo( var 0[1] ); // bat

       echo( my array[1] ); // cat

bat
cat
