The update program below will update the
current version of your product to the latest maintenance release
version. This is only for owners of the same numbered version of
the product. To update, download the update program below and run

The maintenance version is
the alpha character after the version number. It is
displayed in the first line of the banner when the compiler is invoked, as
well as in listing files. The update program will update your product
from any previous maintenance version.
To digress to a previous version, the product
must be reinstalled from the product CD, then the update program for
the desired maintenance release could be run. (Saving downloaded updates
is recommended for this purpose. Previous versions can also be

of the SIZE argument of the RANDOM_SEED subroutine will now be set to
10, rather than 2. The number of default INTEGERs the processor uses to
hold the seed is 10. We recommend source code similar to the following
to reduce the impact of such changes:
PARAMETER ( MAX_SEED_SIZE = 20
INTEGER SEED( MAX_SEED_SIZE ), SIZE
CALL RANDOM_SEED ( SIZE =

Filenames containing spaces
Filenames containing a space character must be enclosed in double
quotes as command line arguments to the compiler, linker, etc.
Lahey ED Developer initialization
The Lahey ED for Windows ini file is now ED4W.ini (the
default name); it was ED4W_ELH.INI previously. When invoking ED4W.EXE,
you do not need to specify an ini file name with the -i switch.
SOLD90 command-line debugger
SOLD90.EXE can only be run on programs linked with the -NWIN option
(note that -WINCONSOLE is the default option).
