matherp said Still works for me

OK, which of these two is the case?

In the filename "01.MyBASICProg.bas"

A. The filename is 01 and the extension is MyBASICProg.bas

B. The filename is 01.MyBASICProg and the extension is .bas

In MS-DOS and Windows, B is the answer.

Asking for a friend...

javavi said @matherp Peter,
Since things are moving forward, can I ask too?
Is it possible to make a built-in calculator for PicoMite, using the CALC command?

A calculator like the one in PicoTop
https://github.com/7west/PicoTop

Please don't ;-) Why else do we have BASIC for writing our own programmes? ;-)
@javavi: This command is very interesting for that:

For calculations, at the prompt I just use

? expression

That is what it does. Don't like it, don't use it. There is no right answer.

Quote OK, which of these two is the case?

The first . character in the filename is treated as the start of the extension. If there is already an extension defined then .bas isn't added. This won't be changing

That doesn't deal with carrying forward the answer as in Javavi's example and my response

For years I have been using:-

> x=5*2 :?x
10
> ?x+10
20
> ' or
> x=x+10 :?x
20
>

It is a bit more typing, though in TeraTerm the " :?x" can be held on the clipboard (highlight with mouse) and applied at the end of every line with Alt-V

And JohnS has reminded me (see below) the up arrow can save some typing on PicoMites.

Then I'd use

x = expression

I probably do it a few times a month at most so I don't need any more of an embedded calculator but maybe others have a need?

If I'm using MMB4L I don't even need to use the above as you can hit uparrow (as many times as you like) and reuse the existing expression(s).

Is there any way to get lines longer than 40 characters LISTed on a PicoCalc? I have a serial printer hooked up and can LIST a program to the serial port but it still wraps at 40 columns even though the printer is an 80-column printer.

JohnS, javavi,

It was meant to be a hint about the possibility of programming a miniCalc yourself

I had the command to hand because I’d been thinking about a ‘programmer’s pocket calculator’ over the last few days.

I just don’t think something like that belongs in the firmware anymore!

Just my two cents.

Matthias

Mini example, without error handling, without parsing the input, etc.:

CLS
Font 1
Dim integer r%
Dim string i$
Do
Input "Calc ";i$
r%=Eval(i$)
Print r%, Hex$(r%), Bin$(r%,16)
Loop

Calc ? 2+3*4
14 E 0000000000001110
Calc ? sin(pi/2)
1 1 0000000000000001
Calc ?

I recommend and use the same.
This is Eval.
I use also On error skip with it, then I can handle alarms without stopping the program (for example syntax, divude by zero, etc.)

...I'm not sure if this has been mentioned before: When you try to open files in the Text Viewer that are smaller than or equal to one page, the Text Viewer closes immediately and you can't view them.
Would it be possible to make it so that the viewer closes only when you press ESC?

Frank

V6.03.00RC3

PicoMiteRP2040V6.03.00RC3.zip

PicoMiteRP2350V6.03.00RC3.zip

Listing a short file in FM now requires a keypress before exiting the listing to avoid it disappearing immediately

Expermental add-ons

All versions:
Calculator immediate mode at the command prompt. Type in calculations and you will get the answer no need for a question mark. The answer will also be stored in a variable MM.ANSWER allowing follow-up calculations. This code is 1: trivial and 2: only gets executed after all normal command line processing has failed, so it should be benign and I will certainly find it useful as well as hopefully javavi

RP2350 versions:
SLEW command

Peter!

Fantastic again, thank you!
What do you think can somehow solve to use string variable to give object name for Astro and Star command?

Peter,

occasionally I get an error in the new calculator mode, e.g.

> sqr(2)
Error : MM.ANSWER is not declared

can dim mm.answer as integer, calc-mode works then and it turn up as a float variable which makes sense.

Currently I'm not able to reproduce it consistently.
