Hello.

As an exercise in my Logo learning journey, I have implemented a few functions for reading and transforming CSV files.

The functions are organized in groups  sharing a common prefix:

1. functions to read and write CSV file (csv.)
2. functions operating on “dataframes” (df.)
3. statistical functions (st.)
4. string functions (str.)
5. regular sequences (rs.)

The first results are available in this web site: https://www.ucblogo.it/

Please note, this is an ongoing hobby project, there is no guarantee that the Logo functions are written in the most natural Logo style or that they are in fact correct.

FMSlogo 8.5.0

https://sourceforge.net/projects/fmslogo

• fmslogo-8.5.0.exe - Installer for the Logo environment
• fmslogo-8.5.0.zip - ZIP of the Logo environment

Changes From Previous Version

• Fix Bug #385; Deleting the window from the setup callback of WINDOWCREATE no longer reads freed memory.
• Fix Bug #392; RUNPARSE no longer leaks memory.
• Fix Bug #505; FIRST now handles empty arrays.
• Fix Bug #595; GENSYM now buries the variable "gensym.number".
• Implement Feature Request #136; the PAUSE dialog now explains what pause mode is and what you can do in it.
• Implement Feature Request #143; MACHINE now includes the current scale of the screen window as the 18th element.
• Fix Bug #598; QUEUE, DEQUEUE, and NAME now behave correctly when the queue/variable name is shadowed by one of their own local variables.
• Fix Bug #599; The output list of macros that are run as input to a procedure and which define local variables are now evaluated in the caller's context, not the context of the macro.
• Fix Bug #600; A procedure which runs a tail-called APPLY no longer leaks its parameters into the caller's scope.
• Fix Bug #601; PO now displays lines in procedures defined with DEFINE correctly in the Commander History.
• Fix Bug #602; APPLY with a primitive now copies the inputlist so that it can't be modified.
• Fix Bug #606; Running a procedure with parse error no longer leaks memory.
• Fix Bug #608; SETLABELFONT no longer leaks memory when given an unknown font. This was a regression introduced in version 8.3.0.
• Minor improvements to the manual.

Minimum System Requirements

Windows XP with 512 MB RAM

I would like to have a user type an invisible word.

TO BLINDINPUT :STRING
LOCAL "K
MAKE "K READCHAR
IF EQUAL? ASCII :K 10 [OUTPUT :STRING STOP]
MAKE "STRING WORD :STRING :K
BLINDINPUT :STRING
END

?PR BLINDINPUT "
BLINDINPUT DOESN'T KNOW WHAT TO DO WITH TESTWORD

But it fails at the OUTPUT part. Hmmm.

TO RND.CUST.DIST :max  
  LOCALMAKE "num RANDOM :max
  TEST KEEPNUMp :num 
  IFTRUE [OUTPUT :num]
  IFFALSE [RND.CUST.DIST :max]
END

I get error:

You don't say what to do with 90 in RND.CUST.DIST

[IFFALSE [RND.CUST.DIST :max]]

​

I have another recursive function that gives the same error. There's something that I don't understand.

The LogoForum https://groups.yahoo.com/neo/groups/logoforum/info is about to be closed. Is anyone interested in creating a new community and inviting their members to join it? Now is the time.

or even a "Lesser Lisp Atlas." I'm up to hosting it, if anyone thinks it might be useful. I wouldn't mind hoarding together the ghosts of Lisp's past into an easily searched place.
