GOAL:

An overview of changes that occurred between Version 6, Version 7 and Version 8 startup parameters.

FIX:

-- VERSION 6

In Version 6 - the following startup parameters are known as
"hard limits". If these hardlimit parameters are exceeded, Progress
will issue a system error and return to the operating system.

Parameter: Description:

-D Directory Size - The number of compiled procedure and
include procedure directory entries.

-e Edit Buffer Size - The size of the edit buffer in 1KB unit

-l Local Buffer Size - The size of the local record buffers
in 1KB units.

-nb Nested Blocks - The maximum number of nested blocks.

-- VERSION 7

The -l (Local Buffer Size) hardlimit has been removed.
As long as the application has the required memory,
Progress will continue to use this memory as the local buffer pool.

The -D (Directory Size), the -nb (Nested Block), and the
-mmax (Maximum Memory) parameters, have all been changed to be
'soft limit' parameters. The -mmax parameter is similar to the
Version 6 parameter, -e (Edit Buffer Size).

'Soft limit' parameters will not cause a system error. Progress will
try to manage the application within the set parameters limits.
If the application needs more resources, Progress will increase the
exceeded limit without issuing a system error.

-- VERSION 8

Startup Parameters, -D (Directory Size), -nb (Nested Block),
-mmax (Maximum Memory), and the -l (Local Buffer Size), have been
re-introduced as 'soft limit' parameters.

To force Progress to adhere to the set limits, Version 8 has a new
startup parameter, -hardlimit. When -hardlimit is specified and one
of the limits is exceeded, Progress will generate a WARNING message
which is written to the current output (if there is current output)
and to the log file (.LG). In addition, Progress issues a message
that a resource limit was reached and raises an untrappable STOP
condition.
