Bug: String Slicing (*solved*)
#1
I think string slicing still has bugs in it. Not quite sure why this fails, but it produces code that runs briefly and crashes, running in Spectaculator:
(fails with or without the DIM statements, but crashes differently in each case)
Code:
DIM A$,p$ as string DIM start,fin as integer 10 LET a$="This is a very long scrolly string that I am going to print" 20 LET start=1 30 LET fin=32 40 LET p$=a$(start TO fin) 50 LET start=start+1 60 LET fin=fin+1 70 IF fin>LEN a$ THEN LET fin=1 : END IF 80 IF start>LEN a$ THEN LET start=1 : END IF 90 PRINT AT 0,0;p$ 100 IF start<fin THEN GO TO 40 : END IF 110 LET p$=a$(start TO )+a$( TO fin) 120 GO TO 50


Correcting the 1 to Zero (Since in compiled code the strings begin slicing at zero) has no effect other than change the way it crashes:

Code:
DIM A$,p$ as string DIM start,fin as integer 10 LET a$="This is a very long scrolly string that I am going to print" 20 LET start=0 30 LET fin=31 40 LET p$=a$(start TO fin) 50 LET start=start+1 60 LET fin=fin+1 70 IF fin>LEN a$ THEN LET fin=0 : END IF 80 IF start>LEN a$ THEN LET start=0 : END IF 90 PRINT AT 0,0;p$ 100 IF start<fin THEN GO TO 40 : END IF 110 LET p$=a$(start TO )+a$( TO fin) 120 GO TO 50
