Charles,
I have redesigned Helm so I can more easily port it to other systems. Though it
is taking a lot longer than I anticipated, I'm planning to have the Windows
version by the end of the year. Because Helm is so complex, I realized that I
probably could not maintain several versions of the same program so I'm working
on a single core that will compile on multiple platforms. This means the Amiga
version will continue to get updated in the future, ports to subsequent OS's
will be much easier, and it also means you will be able to author books on the
Amiga that will run on other platforms.
You can seek to anywhere within a disk file with Helm's seek command. Here are
the descriptions of Helm's IO commands.
open <filename> as <container> [erase]
seek <integer expression> [from]
<start | position | end> [of] <file>
read [from] <file container> for <number of bytes>
read [from] <file container> until <character>
write <expression> to <file container>
Also, Helm 2 will have support for dBase files which will allow you to bind
record fields to Helm objects.
Helm's script language allows the author to specify individual codes in the
form of octal numbers. For instance, to send a 1 followed by a three to the
printer, you can use the following script:
open "prt:" as myprinter
write "\001\003" to myprinter
close myprinter
