Only for conditional operators.

Extract of documentation about KeyPgOpNot : Operator Not (Complement) Returns the bitwise-not (complement) of a numeric value Syntax: declare operator Not ( byref rhs as byte ) as integer declare operator Not ( byref rhs as ubyte ) as integer declare operator Not ( byref rhs as single ) as integer ...

I think that behavior is linked with this topic:
DOCUMENTATION / Implicit Conversion from String to Zstring Ptr for Argument

Try to declare 'pixels' as a 'short ptr':

A small variant: Function multiply (Byval a As Integer, Byval b As Integer) As Integer Dim As Integer c For I As Integer = 0 to 31 If Bit(b, I) then c += a End If a Shl= 1 Next I Function = c End Function Dim As Integer a = 1234, b = 5678 Print a * b Print multiply(a, b) Sleep

... is there a correct formula to mul (a x b) by just shifting ??? and summing. Function multiply (Byval a As Integer, Byval b As Integer) As Integer Dim As Integer c For I As Integer = 0 to 31 If Bit(b, I) then c += a Shl I End If Next I Function = c End Function Dim As Integer a = 1234, b = 5678 ...

Can you do something about it?

Thank you very much for removing these warnings.
This is much nicer now!

'Byref returns' can also be used by operators to return references (added a sentence in documentation: BYREF (function results) ) The following example is the implementing of a simple smart pointer: - A smart pointer is an object which behaves like a pointer but does more than a pointer. - This obj...

You cannot declare a variable with a name that would be the value from another string variable.
Any symbol-name must be directly provided to compiler by means of alphanumeric characters text.
Even the contents of a constant string cannot used to declare a new variable name.

'cntr31' must be defined and assigned to a value before your 'dim' declaration.

Example:

I suppose this refers to: XFont Text Render Library [v11.9.13]

Dowload the library for win (for example), and copy:
- 'xfont.bi' into ...\freebasic\inc
- 'libxfont.a' into ...\freebasic\lib\win32

Have you tested your program !!!

pos += 1
n += 1

oFile.ListFiles("\pages", "txt", page_list())
Why 'oFile.' ?

I want to know if my code it's fine, I need to retrieve a list of files of a folder and return it to a var-len array. Have you tried to correct at least the errors detected at compile time? Just a quick glance at your program! Sub ListFiles(byref path As String, byref extension As String, file() As...

Any (already experienced) programmer knows that the copy constructor is always called by the compiler when a variable is passed to a procedure by value, or a result is returned from a procedure by value: - But in the latter case of returning by value, the copy constructor is called only if the 'Ret...
