BUG #1 with new STRING*N (which I had difficulty identifying in a large code which no longer works) Assigning a STRING * N variable, by an expression which is a concatenation including at least one string variable (whatever its type), does not work. Example: Dim As String * 10 s Dim As String s0 = ...

No, simply replace ’ with ' !

@ Jeff , - internal: types containing only STRING*N fields or child types containing only STRING*N fields will initialize to spaces using a memory fill operation, and where other data types are present will induce the creation of an implicit constructor Maybe simpler to always create at least one im...

Change : STRING*N occupies N bytes and has no terminating null character At first glance, list of pages that will need to be updated: KeyPgType LangQB KeyPgString KeyPgOpStrptr ProPgStringsTypes KeyPgSizeof KeyPgSwap KeyPgDim TblVarTypes + ProPgInitialization KeyPgUnion KeyPgByref I think I will st...

@Jeff,

limit WSTRING*N, ZSTRING*N, STRING*N types to 2^31-1 and show an 'invalid size' error if the size given is less than 1 or greater than the limit

Could you confirm the theoretical limits for a var-len string:
between 0, and 2^31-1 (for 32-bit) or 2^63-1 (for 64-bit) ?

Initialization/Assignment of an old/new fix-len string through a string literal expression The behavior seems to have improved: Dim As String * 20 s1 = "Alpha" + Chr(0) + "Beta" Print "'" & s1 & "'" Dim As String * 20 s2 s2 = "Alpha" + Chr(0...

Assignment of an old/new fix-len string through a function by a 'Byref' parameter or a 'Byref return The behavior of this type of assignment seems even more (last test) degraded for the 'Byref' return case: Function test1(Byref s As String) Byref As String s = "1" Return s End Function Pr...

Pointer to a new fix-len string Warning: dereferencing a pointer to a fix-len string (with the new definition) can lead to an extension of the string by some pollution, or even an outright crash. Type UDT Field = 1 Dim As String * 5 s = "123" Dim As Ulong I = &h44434241 Dim As Ubyte N...

'Concatenate and Assign' versus old/new fix-len strings Due to the definition change on fix-len strings, the 'concatenate and assign' no longer works as before (as they do on previous defined fix-len strings). Workaround for compatibility with both fix-len string definitions: Dim As String * 9 s1 =...

fbc: STRING*N occupies N bytes and has no terminating null character ..... SWAP will pad values with spaces where one of the arguments is of the STRING*N data type ..... OK: Dim As String * 4 s1 = "123" Dim As String * 6 s2 = "ABCDE" Print "'" & s1 & "'&qu...

Fixes and improvements soon; just waiting for the test-suite to finish....again. I was debugging fbc only to find I had made a badly written test. OK, now Plus a test to avoid overflow on the fix-len string when it is passed to a procedure by 'Byref As Zstring' ? Yes, compared with fbc 1.10.0, ther...

Works only with 'gas' and 'gas64' that accept modifications in a section of constant data ('.data section').

I have already seen it :

Your terminology is correct:

Changes for string*n are now merged to fbc/master 1) A fix-len string member field is not initialized with spaces. Implicit constructor to add ? 2) A fix-len string passed to a procedure by 'Byref As Zstring' is not modified (this works with 'Byref As String' ). Plus a test to avoid overflow on the...
