[Gambas-user] Maybe a bug with val functiun

[Olivier Coquet]

i think i've detected a bug in the Val() function gambas V0.71 on RH9

i'll try to be clare but........

if you use the val() function on a variable called num
like this:

i=val(num)

if num is = to "123" all is ok, but if num="ert" sometime this result in NULL 
for i, sometime this result in an error mismatch date, num or boolean 
expected.

i've seen that in a fct writed for my convenience I give you the complete code 
to reproduct the error.
Note than if the fct is executed correctly for the first time, second time 
never generate an error, and if the code is executed with error the first 
time, second time generate allway an error.......!!!!!

start of code..........

PUBLIC FUNCTION dte_conv(dte AS String, rev AS Boolean) AS String
' Fonction de convertion de date, si rev = true format = bdd
' si rev = false format à la française
  DIM m AS String
  DIM j AS String
  DIM y AS String
  
  m=""
  j=""
  y=""
    
  IF rev = FALSE THEN
  
    j = Left$(dte,2)
    m = Mid$(dte,4,2)
    y = Right$(dte,2)
    
      IF (Val(j) > 31) OR (Val(m) > 12)THEN
        RETURN ("")
      ELSE
        RETURN (m & "-" & j & "-" & y)
      ENDIF

    
  ELSE
  
    m = Left$(dte,2)
    j = Mid$(dte,4,2)
    y = Right$(dte,2)
    

      IF (Val(j) > 31) OR (Val(m) > 12)THEN
        RETURN ("")
      ELSE
        RETURN (j & "-" & m & "-" & y)
      ENDIF

    
    
  ENDIF
END

........end of code
