In priority order:

1. Ability to load programs via WiFi-to-serial and Ethernet-to-serial converters such as Lantronix WiPort and XPort and Moxa NPort.

2. Support for simple structures.

3. Library routines for incr(any-numeric-type) and decr(), or better yet, language support the ++ and -- operators

4. Library support for equivalents to C's atoi() and atol()

I assume you mean for the case if they don't support the DTR line and you have to use some special character sequence in the serial stream to initiate a download.

Yup. I already suggested that to Don.

If you write the code i = i + 1 where i is a global variable results in a single increment instruction for a byte, integer or long. The ++/-- operators are from C and would be strange to a Basic programmer. Then you may also get into all the problems of prefix and postfix increment.

The system library function ValueS() gets you partway there. I personally have not needed to do much string manipulation and try to avoid it - that is one way to use up stack space and memory.

Re (1)- Most of these (Moxa, Lantronix, MaxStream) have DTR remoted via their virtual COM driver for Windows, but the timing may be not what ZBasic wants. Example: Moxa NPort sets DTR true when the virutal COMn is opend, and false when closed. During the connection, they say DTR can be changed, but I have yet to get that to work. And the timing may not be what ZBasic
s bootstrap loader expects.

re (2) Thinks like date/time sure could use a structure.

Well - as to (1) below - I reflashed/reconfigured the Moxa NPort W2150 Wireless LAN (WiFi) to serial RS232 bridge. Now I am able to download code to the ZX24 from the IDE! I don't know why this fixed it, but now DTR toggles like it should.

I'll try the Lantronix WiPort.
