11.2 Generation of Directives from the Symbol Table

The symbol table is used to generate directives. Thus if A is entered in the symbol table with class equal to variable, and attribute type equal to integer, then the directive which allocates space for an integer is generated.

Example 1 shows directives for integers for a number of machines.

Example 1 Directives from a symbol table entry for a name with class = variable, type = integer, and character string A 

 	On an 86-family:	A	DW	?
 	On a M68000:		A	DS.L
