Getting a bit tangled with labels used by GO SUB

Are their any examples of working subroutines anywhere ?

ditto for reading and writing very simple data stream files.

Many thanks !

Magic !

On yet another matter:-

Can I generate a file of data, results of a series of calculations and save it in ASCII easily ?

Is that possible ?

Tim

Changing the subject a tad, one of the aims is to drive external devices through the GPIO port.

Can SpecBAS address these ports and read from them ?

: )

Brill found it !

Now I saved it as ASCII and used Leafpad to add a line.

SpecBAS locked up when I tried to load it.

How to I recover from there ?

Will SpecBAS reject ASCII files ?

A puzzled,

PS the source files for a saved program:-

Which directory are they saved in and are they pain txt files ?

timmoore46

Wow ! It works ! from LXTerminal I added a few extra lines before I started:- cd home cd pi cd Desktop cd foldername from there, I followed the excellent instructions taking great care over upper and lower case ! I used the bash 'ls' command to check I was in the correct directort with expected file...

Many many many thanks both of you ! Mega Brilliant !

I will try that out and see if I can get it to work !

Seems a fun thing from https://sites.google.com/site/pauldunn/ I've followed all the instructions but.... I got lost in Bash and the GUI I down loaded the files on another PC and put them on am SD card. I then copied them onto a Directory on the GUI Desktop AOK then I wanted to copy them to Pi Bash ...

I just download draft Issue 6 and Lo it had a print button ! And it was well behaved ! Printed page 10 to 11 very clearly.

Lack of hardcopy has been a major pain until now.

It may be well known but its was news to me !

I'll bring along a project of Bash scripts (like M$ BAT files or ICL macro files- I hope ! ), as I've zero experience of these any help warmly appreciated !

Its to control the hardware ports.

For the first time visit, the favoured table is found by going in the entrance from the road and its on a raised platform opposite the first part of a very long bar ! An A4 picture of a Raspberry may be found flat on the table or in the vertical 'menu' holder. Also a warm and friendly welcome is ass...

Gulp ! Is this a hoax ? Maybe not !

Hope its still on, as I'm showing up tonight 7pm.

Many many thanks for that most useful info and sample program !

(too much machine code programming a million years ago ! *LOL* )

Very greatly appreciated !

I've done this twice and so far a re-install of Raspbian was the fix, loosing all my data and settings. first I installed 'LXmusic' then I copied about 2GB of mp3 onto the SD 16GB card into a 'My Music' directory on the Desktop, Then foolishly, *LOL*, I set LXMusic's Playlist play to one of the sub ...

timmoore46

Just about ! *LOL*

Many thanks for that tip ! Very greatly appreciated !

Oh Dear ! I just want to write a program that can be used time and time again ! Namely turn on an external GPIO port and check that its working by reading an input. (for as many ports that are available) If I can get one pair of ports working then the rest should be identical apart from port numbers...

timmoore46

I'm sure that is wise advice, but this is what I tried earlier today. Many thanks ! Top Level Module 'Run' program __ Import T1 Import T2 Print ("END) __ Second level Module:- called 'T1' # Print T1 print ("T1") return __ Second level Module:- called 'T2' # Print T1 print ("T1") return __ Naturally ...

I'll start looking at Modules, as it may be an easier stating point than functions !

Many many thanks , as I'm very nervous starting a new language !

I'm used to keeping the primary code as short as possible and keeping all the tricky parts in subroutines . Its very fast on processor power and makes the code a lot easier to maintain and debug. But I'm very very new toPython and very unfamiliar with it. Does Python have any thing similar ? And wha...

timmoore46

On the very first Boot it pops up and is brill !

But if later you want to return to it, how is that achieved ?

Tim

timmoore46

Many many thanks, that is exactly what I needed to know !

Tim

timmoore46

So to ask what must be a silly question, but from Bash how do I get the latest updates etc into Raspbian ?

Sudo ??????

I'm just after getting the least buggy and the best behaved version ! *LOL* And I'm a very long way of being a Bash expert !
