Traced the problem - it is not character set or browser.
This code works correctly

Code: Select alla$ = "z" & "=" & "z"
wprint "a$ is "
wprint a$
wprint "<br>"
wprint "length of a$ is "
wprint len(a$)
wprint "<br>"
end


with the result:-

Code: Select alla$ is z=z
length of a$ is 3


and this code adds the extra spaces - so looks like a parsing fault?

Code: Select alla$= "z" & "=" & "z"
wprint "a$ is "
wprint a$
wprint "<br>"
wprint "length of a$ is "
wprint len(a$)
wprint "<br>"
end


the result is:-

Code: Select alla$ is z = z
length of a$ is 5


Anyway, I know how to get round it now...

Where to get modules?

- Mon Jan 09, 2017 2:57 pm #60747 Ok - I had reflashed the nodemcu yesterday but did not re-format.
Tried that, as you suggested but the esptool just crashes when pressing the format button. I was able to format using the old version 2 flasher and then re-flashed v3a65.
Unfortunately no change:-
a$= at the start of the line causes the contents of the string to be padded while a$ = does not trigger the fault.

The effect is the same on another ESP-01 I tried.

Spaces are ignored in expressions, except before the '=' sign in assignments:
A = 5 + 3 is OK
A =5+3 is OK
A=5 + 3 is NOT OK
A=5+3 is NOT OK

This may be the problem here.
