attempt to SORT drops the last character from original given

[jarych]

Here is a sample program for sorting but it is dropping the last character of any given string. I looked and thought but do not know why. No matter what string to sort the characters given, the very last character is lost.
Maybe someone can find why.

What I try to make the program do:
User give a word or some aphabetical string.
Put the string characters in order into an array.
SORT the array holding the characters into alphabetical order.

variable called flagswitched is to help to know when the WHILE loop does not need
to be repeated.

dim gave$(80)
input "give us a nice string.  ";phrase$

sz=len(phrase$)
for i=1 to sz-1
gave$(i)=mid$(phrase$,i,1)
next i

flagswitched=1
while flagswitched=1
   flagswitched=0
for i0=1 to sz-1
   if gave$(i0)>gave$(i0+1) then
   let tmp$=gave$(i0)
   let gave$(i0)=gave$(i0+1)
   let gave$(i0+1)=tmp$
   flagswitched=1
   end if
next i0
wend

print "SEE RESULTS "
for i1=1 to sz
print gave$(i1);
next i1
print

END

FOUND THE PROBLEM. This next one after modification works.

dim gave$(80)
input "give us a nice string.  ";phrase$

sz=len(phrase$)
for i=1 to sz
gave$(i)=mid$(phrase$,i,1)
next i

flagswitched=1
while flagswitched=1
   flagswitched=0
for i0=1 to sz-1
   if gave$(i0)>gave$(i0+1) then
   let tmp$=gave$(i0)
   let gave$(i0)=gave$(i0+1)
   let gave$(i0+1)=tmp$
   flagswitched=1
   end if
next i0
wend



print "SEE RESULTS "
for i1=1 to sz
print gave$(i1);
next i1
print

END


'superstupid way two for loops
for i0=1 to sz-1
for i1=1 to sz-1
if gave$(i1)>gave$(i1+1) then
tmp$=gave$(i1)
gave$(i1)=gave$(i1+1)
gave$(i1+1)=tmp$
end if
next i1
next i0


Not all of the code and its history was taken out. The two FOR loops were an intermediary try only, and while did not hurt, were not part of the problem.

The problem was in the code section which filled the array, gave$(). Loop limit was cutting off the last character, because my thoughts were confused between assigning the array elements and performing the sorting. I had previously in the assigning part, this faulty code:

sz=len(phrase$)
for i=1 to sz-1
gave$(i)=mid$(phrase$,i,1)
next i
