Jim Thanks for that - side effect of implementing the forced exponential format The Pi version needs updating with all the changes - I'll post something later today Attached is the latest re-release 5.3.17 for the 100 and 144-pin parts 2017-04-19_075342_MMX5.3.17.zip And for the 64-pin part 2017-04-19_075239_MMX645.3.17.zip |

That works better!. I knew I had another program somewhere for engineering notation.

Hello Peter/Geoff. do you have any plans to increase the size of strings in MMBasic now that we have devices that support much larger memories. Even 1K would be nice, 64K would be amazing. I have used the large string support with CFunctions etc but it is a bit "clunky". just asking |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 8572 |
It would be a huge change which would likely introduce bugs throughout the code. Basic strings are stored with a single character length field in the first location giving lengths of 1 to 255. |

I figured as much really - it is sort of "hard baked" in the core of things I guess... dunt hurt to ask though  not like its a show stopper.Thanks Peter. |

There's a problem when printing zero with the new STR$ function.

Can you confirm you are using the new forced exponential format "str$(a,b,-c)" ? |
||||
| cdeagle Senior Member Joined: 22/06/2014 Location: United StatesPosts: 261 |
Peter, Here's the code snippet that prints the numbers. print "position vector x-component ", str$(r(1), 0, -15), " kilometers" print "position vector y-component ", str$(r(2), 0, -15), " kilometers" print "position vector z-component ", str$(r(3), 0, -15), " kilometers" |

Attached is the latest release 5.3.19 for the 100 and 144-pin parts 2017-05-08_175002_MMX5.3.19.zip And for the 64-pin part 2017-05-08_175213_MMX645.3.19.zip This release includes a couple of requested items as follows: 100/144 pin only: GUI VGA OFF 'turns off the VGA output to allow a monitor to go to sleep GUI VGA ON 'turns the monitor back on again Note the memory image of the screen is maintained and can even be updated when the screen is off All versions: OPTION SERIAL PULLUP DISABLE 'permanently stored option that disables pullups on all serial ports OPTION SERIAL PULLUP ENABLE 'default: permanently stored option that enables pullups on all serial ports The OPTION SERIAL PULLUP command should be run once and then the status will be remembered (unless the chip is re-flashed. The option affects all serial ports (com1 - com4) but not the console. In addition there is a bug fix relating to passing a float in an array element to a subroutine requiring an integer |

Attached is the latest release 5.3.20 for the 100 and 144-pin parts 2017-05-12_160746_MMX5.3.20.zip And for the 64-pin part 2017-05-12_160859_MMX645.3.20.zip This now allows xmodem send and receive of files to be called from within a program. Of course normal use of XMODEM to load a program cannot be used in this way In addition, this version implements a complete set of routines for handling long strings. These are taken from Geoff's long string CFunctions, but because CFunctions are difficult/impossible in the MMX they are included in the firmware. The syntax is pretty much the same as the CFunctions although the way they are called is somewhat different. Geoff's document is attached: 2017-05-12_161240_Long_Strings.pdf and the changes are best understood by my test program. There is one additional routine which allows you to substitute characters into an existing string LONGSTRING REPLACE array%() , newstring$, start-position Note that unlike the CFunctions these calls all use integer arrays to hold the long strings. The calls all check for the arrays being big enough and give an error if any call would exceed the array limits. Dim a%(100) 'enough for 800 character string Dim b%(10) LongString load a%(),16,"1234567890abcdef" Print "chars 4-9 are: ", LGetStr$(a%(),4,6) s$="ABCDEFGHIJKLMNOPQRSTUVWXYZ" LongString append a%(),s$ Print "stringlength now :", LLen(a%()) If LInStr(a%(),"ghij") Then Print "ghij found" Else Print "ghij not found" EndIf Print "convert string to lower case" LongString lcase a%() If LInStr(a%(),"ghij") Then Print "ghij now found" Else Print "ghij now not found" EndIf LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ LongString append a%(),s$ Print "stringlength now :", LLen(a%()) start=1 Do p=LInStr(a%(),"ABC",start) If p Then Print "ABC found at position ",p start=p+1 Loop While p>0 Print "Convert to upper case" LongString ucase a%() p=LInStr(a%(),"ABC",start) If p Then Print "ABC now found at position ",p LongString left b%(),a%(),20 Print "left-most 20 characters of a% are ",LGetStr$(b%(),1,20) LongString right b%(),a%(),20 Print "right-most 20 characters of a% are ",LGetStr$(b%(),1,20) LongString mid b%(),a%(),20,20 Print "chars 20-39 characters of a% are ",LGetStr$(b%(),1,20) Print "Now clear a%" LongString clear a%() Print "a% is now ",LLen(a%()), " characters long" Print "copy b% to a%" LongString copy a%(),b%() If LCompare(a%(),b%())=0 Then Print "Compare :the strings are the same" Print "a% is now ",LLen(a%()), " characters long" LongString concat a%(),b%() Print "a% is now ",LLen(a%()), " characters long" If LCompare(a%(),b%())=1 Then Print "a% now bigger than b%" If LCompare(b%(),a%())=-1 Then Print "b% now smaller than a%" Print "b% is currently ",LGetStr$(b%(),1,30) LongString replace b%(),"hello",5 Print "b% is now ",LGetStr$(b%(),1,30) |

After a successful XMODEM SEND file from within a program, control C doesn't work. If you abort a transfer or let it time out by starting but not responding, ^C works. To get control back, I started a second transfer and the aborted with three ^X's Jim VK7JH MMedit MMBasic Help |
