from CHAIN.COM?
The memory it refers to is called the stack by CHAIN.COM (you will see the
'remaining stack' when you type CHAIN without parameters), but you may know
it better as the DOS environment space
Unfortunately, it seems that the environment space is trimmed when a DOS
command session is opened, at least I have not been able to increase this
space before the session is opened
So the trick is to increase the available environment space inside the DOS
session until it is 'enough' for CHAIN.COM. How much is enough? As a rule
of thumb the 'remaining stack' when you type CHAIN without parameters must
1200 or more.
So how do you increase the available environment space?
The only method I found is to reduce the length (and sometimes the number)
of the environment variables. When a command session is opened it makes a
local copy of those variables, so you can trim and/or remove all the
variables you don't for the program you are running.
A good place to start is usually the PATH command. I assume you use a
batchfile to call CHAIN.COM (if you don't, create one). Inside this
batchfile, before the line where you call CHAIN.COM, set the PATH to the
minimum directories you need for your program.
If trimming and/or removing the existing environment variables is not
enough (remaining stack stays below 1200), the next step is to create some
dummy environment variables in your window environment (e/g DUMMY1, DUMMY2
etc), and to set them to 250 characters each in the windows environment.
When you open a DOS session the local copies of those variables will be
available for you to remove.
