str_GetW() is a great call  .
A lot of the string processing on my ardunio moved to GFX.
However there is a strange bug/Behaviour
If str_GetW() encounters a 0 in the string it does not convert it and status returned is 0 (fail)
for e.g E06|00|16
works great till the first pipe (|) and returns 6 as expected , then for the next two chars it fails (returns 0) and value in the &var remains unchnaged
then after the second | it work correctly and returns 16
I assumed that if it encounters 0 it will conver all 0's to 0 move the pointer to the second pipe and return success ( 1)
or is the current behaviour the "provided" behaviour
Regards

Hi,
str_GetW is working as intended, here is an example that checks it.
var c, p, n;
var string[10];
to(string); putstr("E06|00|16");
p := str_Ptr(string);
repeat
if (str_GetW(&p, &n))
print("number ", n, "\n");
else if (str_GetC(&p, &c))
print("character ", [CHR] c, "\n");
else
break;
endif
forever
repeat forever
result is:-
character E
number 6
character |
number 0
character |
number 16

My sample was incorrect,
change it to
putstr("E06|0|16");
character E
number 6
character |
character 0 (it should have detected as number)
character |
number 16

Hi, yes unfortunately you are correct, will not work for a single zero followed by a character that is > 0x21 (space).
The only temporary workaround is to follow any single zero's with a space.
It will be fixed in the next PmmC release
