TN100D.txt DATA SEGMENT USAGE OF SYSTEM UNITS
Category :Pascal
Platform :All
Product :Turbo Pascal 5.0 5.5
Description:
Q. How much of the 64K in the data segment is actually
available to my program?
A. The amount of data segment used by the run-time library
depends on which standard units you use in your program. Here
is the data segment usage (in bytes) for each unit:
UNIT Data Size
---- ---------
System 664
Overlay 10
Crt 20
Dos 6
Printer 256
Graph 1070
Turbo3 256
Graph3 0
=========
2282
The total size of the data segment is 65,520 bytes. If you
used only the System unit, the amount of data segment space
left over would be
65520 - 664 = 64856 bytes
