    Number to increasing string

    Hello ...

    I have Made a little example with increasing number and autoconverts to a String but found perhaps a Bug?

    uses "ui" 
    long flag = 10
    flag++
    msgbox str$(flag) '11
    'thinbasic result 10 ?
    '
    ' number to an increasing string
    '
    '1)
    string s = "200"
    s = val(s)+1 '201
    msgbox  s 'result: "201"
    'thinbasic result: 2001
    
    '2)
    long k
    k++
    s = val(s)+k
    msgbox s 'result: "202"
    'thinbasic result : 2001
    
    '3)
    string m = " Mona"
    string st = "3000 " + m
    st = val(st)+1
    msgbox st + m 'result: 3001 Mona
    'thinbasic result: 30001
    
    '4)
    long km = 100
    km++
    string m =" Mona"
    string sr ="3000 " + m
    sr = val(sr) + val(km)+1
    msgbox sr + m 'result: 3102 Mona
    'thinbasic result: 30001001

    you can't always get what you want, but if you try sometimes you might find, you get what you need

    First of all, thanks for testing, it is always usefull.

    To me all exposes cases are as expected.

    ++ is not supported by thinBasic, at the moment it is just ignored.
    All the other cases ... if thinBasic expects a string, math is for string so + is considered "concatenation" even if before there is a VAL

    If you need to sum a number into to a string that represent a number, use a numeric variable as destination like:
    long n
    string s = "200"
    n = val(s)+1
    msgbox  0, n
    
    Which math to follow (numeric + or + as string concatenation) depends by the destination type
