[ql-users] Sbasic and slicing

[François Van Emelen]

Hi all,
Could someone explain me this?
P1
100 a$="SMSQE"
110 b$=a$(4 to 3)
120 print b$,len(b$)
Line 120 prints an empty string with length 0.

P2
100 a$="SMSQE"
110 b$=a$(4 to 2)
120 print b$,len(b$)
Line 120 returns the error 'unacceptable array index list'

Question: Why doesn't P1 return the same error as P2?

Any ideas?
