/********************************************************************
|
|
|
49 |
The following types store the symbolic information for each table
|
|
|
50 |
in the .T file. They consist of a count of the number of elements
|
|
|
51 |
(num,noofsyms) or size (usage) in the case of strings. This is followed
|
|
|
52 |
by a pointer to a fixed number of elements of the appropriate type . The
|
|
|
53 |
size of this space is given by the appropriate macro at the end of this file.
|
|
|
54 |
Consequently, when the number of elements in the table exceeds this fixed size
|
|
|
55 |
a new array is set up and pointed to by the nextsyms or overspill field.
|
|
|
56 |
This mechanism is transparent to the caller of the symbol table routines
|
|
|
57 |
given in new_symbol.c
