not me

[Theo Gottwald]

Anybody else has problems editing past posts?
Please tell me  I need to know.

[Johan Klassen]

I also can't edit my previous post, but I can edit this post

[Theo Gottwald]

Possibly then Posts can only be edited for some time?
Lets watch it for a while before i try to find out where the problem is.

Hi Theo,
as I told you until 29/3 I was able to edit it, now it won't let me anymore.
Could it be because it started a long time ago?

[Johan Klassen]

Possibly then Posts can only be edited for some time?

I think that you can edit your post as long as there are no subsequent post following the post
for example, I no longer can edit my post above

[Nicola]

Hi Johan,
No, it's not like that because in this post there was only my beginning, and despite this it was not possible for me to edit it.

Try this HTML help file; 
it should open in any browser. The file data.js contains oxyKeyw. 
They must be in the same folder. It should also work on smartphones.

Cheers

[Charles Pegge]

Thanks Nicola. Very interesting.
I found that the JSON data does not tolerate line breaks in the field data but it will support <br >

For instance in the redim entry in OxyDatabase.txt

Code Select Expand

key:      "redim 18"
action:  create or resize a dynamic array, preserving contents within range
use:      extend or reduce an array size at run-time
example: 
  redim string s(n)
  redim string s(1000)
  redim string s(100) clear
  int y=100, x=100
  redim int a2d (y,x)

  'use [redim] when passing to a procedure:

  sub f(int *fa2d[redim], int y, x)
    redim fa2d(y,x)
  end sub
  ...
  del a2d
remarks: 
  The remaining element values are preserved unless
  the 'clear' directive is given.

  redim cannot be directly used inside a Type or Class.
related:  remap, dim, dyn, lbound, ubound, del, new, indexbase
group:    system macro
updated:  02/03/2025

in data.js redim with multi-line example:

Code Select Expand

  {"id":"redim","group":"system macro","action":"create or resize a dynamic array, preserving contents within range","use":"extend or reduce an array size at run-time","related":"dim, new, indexbase","example":"  redim string s(n)<br> redim string s(1000)<br>  redim string s(100) clear<br>  int y=100, x=100<br>  redim int a2d (y,x)<br>"},
