Before You Begin
Strategy size limits are determined by the amount of total System Memory available. System Memory includes conventional
memory, Expanded Memory (LIM 4.0 EMS), and eXtended
Memory (XMS). After you determine how much conventional
memory is available, estimate the size of the planned strategy.
Details on estimating strategy size can be found in Appendix E:
Estimating Database Size. I/O compatibility is also discussed
in the section, I/O Considerations.
A rule of thumb is that you can run a strategy containing 1000
algorithm blocks with 550 K of available conventional memory.
If your strategy and the system you are going to run it on meet
this requirement you can bypass the next two sections.

You can check available conventional memory by typing
CHKDSK at the DOS prompt. The DOS CHKDSK utility
gives you information on the disk drive currently active as well
as a reading of conventional memory available (Figure 3.1).
