LibreLogo - Error

users
#1

Write the following:

:x = INPUT "Length?"
FORWARD 50
FORWARD :x
FORWARD 50

This should draw a straight line. 50 + :x + 50 pixels long.
Instead of stepping forwards :x pixels the turtle writes the number from the input box . The turtle also render a line under the number and continues the next command from this point.

I think this is a bug, but to be sure I hope others can verify this.

LibreOffice 5.0.3.2, Windows 7, English.
Not tried for other versions.

I tried executing the first line and got the error message
'Error (in line 1)'

LibreOffice 5.0.4.1 under LinuxMint 17.2

Perhaps not a bug.
It looks like the INPUT command returns a string. Therefore
:x = INT INPUT = 'Length?'
works as expected.

If I write FORWARD 'This is a text', the turtle writes the text together with a line. I expected an error message saying "Not a number" or something like this.

I do not know why you get the error message. It works on my computer. (Assuming you are running LibreLogo in Writer.)
