I recently helped to install Icon on the University's Sequent Symmetry S81 and then put on some workshops to 'educate the masses'. I'm now being inundated with questions from people who were so impressed they got a copy to run on their PCs. They're now coming to me with questions about the implementation that I cannot answer. Anyone care to help? 1) Is there a PC version of icon which creates an executable file instead of having to run the ICONCX program every time? 2) Text files which I want to process using icon involve home-made fonts created in Pascal. What is the possibility of processing such fonts in icon? 3) I keep getting an error message 'inadequate space in block region'. Is there an environment variable that can be set to stop this? This happens with long files. Thanks in advance for any light shed on these problems.

The default on the system I use (3B2) is 51,200 so I use 100,000 when I start to get the block region warning. Jerry Nowlin

Unfortunately, I have my doubts as to whether most MS-DOS Icon implementations can support HEAPSIZE values larger than 64K due to the segmentation of the 8086 architecture. Large Icon programs have to be designed well in order to run under MS-DOS. Version 8.0 of Icon is more space-efficient in its use of the block region.

Regarding Icon version 8.0. Is it available yet, if not then when, and what new features, fixes will it provide? thanks chris ------- |~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~|~~~~~~~~~~~~~~~~~~~~~~~~~| | Christopher J. M.

Version 8 of Icon will be released on a system-by-system basis as we get individual implementations and documentation done. We expect to release Version 8 for UNIX and VMS in a few weeks. Others will follow as time and resources permit. We'll provide a summary of new features and other relevant information when the first release is announced.

I use custom made characters on my Zenith by loading a table of
chars 128-255 into memory, then going to the graphics screen with
writes("\e[=6h")
I first install the ANSI.SYS terminal driver by including the
relevant command in the CONFIG.SYS file.
