To select the swap method:
1. Highlight Swap method .
2. Select the desired Swap method.
After selecting the Swap method , move to Memory required .
Memory Required Selection
The
Memory required
option in this dialog box refers to how much memory is
required to run your user-defined program. The BASIC Development Software
checks its available memory before attempting to run the user-defined program. If
the amount of available memory is greater than the amount specified by this
option, then the BASIC Development Software will not swap itself out to EMS or
disk.
To select
Memory required
:
1. Highlight Memory required .
2. Enter the amount of memory required for your user-defined program.
After selecting the amount of memory required, move down to Options .
Table 5.2 Swap Method Options
Option Description
No swap when executing a user-defined program, no additional memory is
freed up by swapping BASIC Development Software out to disk or
EMS. EMS refers to your computer’s expanded memory, if it has
any.
To disk only when executing a user-defined program, additional memory is freed
up by swapping BASIC Development Software out to disk.
To EMS only when executing a user-defined program, additional memory is freed
up by swapping BASIC Development Software out to EMS.
To EMS then to disk when executing a user-defined program, additional memory is freed
up by swapping BASIC Development Software out to EMS first and
then to disk.
Use default method the swap method used is the same as selected for Shelling to DOS
IMPORTANT
You may select a user-defined program that was executed with no
problems before, and find that it is now too large for you personal
computer’s RAM memory. This is because the program now has
to share RAM memory with the BASIC Development Software.
For large RAM memory-consuming files, you generally have to
select the To EMS or To disk only options when adding those
files to the User menu.
