Crash in PBDLL

[Edwin Knoppert]

This will crash:
Just to let you know..
(Useless code anyway)

#Compile Exe
 
Function PbMain
 
    MsgBox Str$( Len( "123" ) + Len( "234" ) )
 
End Function

And somethimes this too:

#Compile Exe
 
Function PbMain
 
    Dim T1 As String
    Dim T2 As String
 
'    T1 = "123"
'    T2 = "234"
 
    MsgBox Str$( Len( "123" ) + Len( "234" ) )
 
    MsgBox Str$( Len( T1 ) & Len( T2 ) )
 
End Function

module WGFWER.EXE op014f:00401981

IIRC, LEN("literal") seems to be the killer. I think this has been reported before in a slightly different context.

Yes, LEN() currently does not work on a string literal, and this has been discussed a few times before on this BBS.

Since the length of a literal is known by the programmer (before compilation), it is more efficient to hard-code the length value instead of making a run-time calculation on the hard-coded string literal.

That said, R&D have told me that LEN() will be made to work with a string literal in the next update to the compiler.

Thanks!
