    char **argv

    I thought that this means a pointer to a pointer to an ASCIIZ string...
    It does

    Hmm... I'll take a look at this later tonight.
    Thanks for your help

    Guys --
    That "string" works confirms Lance's idea. (pointer to pointer of ASCIIZ).
    What means address of STRING in PB ?
    This is an address of pointer, which shows, where located
    string data (ASCIIZ).
    Pls, test
    Code:
    #Compile Exe
    #Register None
    #Dim All
    #Include "win32api.INC"
    Function PbMain
       Dim s(1 : 2) As String, i As Integer, ss As Dword
       s$(1) = "abc": s$(2) = "cde"
       For i = 1 To 2
          ss = CvDwd(Peek$(VarPtr(s$(i)), 4))
          MsgBox Hex$(ss) + "/" + Hex$(StrPtr(s$(i))) + "/" + _
              Peek$(ss, 3) + "/" + Str$(Peek(ss + 3))
       Next
    End Function

    You are correct - about rule,but practice show different...

    try this example

    glutinit 1,"t"

    DECLARE SUB glutInit LIB "glut32.dll" ALIAS "glutInit" (argcp AS LONG, argv AS asciiz)

    and try
    glutinit 1,"t"

    DECLARE SUB glutInit LIB "glut32.dll" ALIAS "glutInit" (argcp AS LONG, argv AS string)

    Single program is worked without initglut.

    You can try translate code C to PB
    examle- =ATLANTIS.C= 1994, Silicon Graphics, Inc.

    char **argv

    I thought that this means a pointer to a pointer to an ASCIIZ string... ie, two layers of indirection. In PB, you do multiple layers of indirection like this:

    'Psuedocode:
    DIM a AS ASCIIZ
    DIM b AS ASCIIZ PTR
    DIM c AS ASCIIZ PTR
    b = VARPTR(a)
    c = VARPTR(b)
    MSGBOX a & $CRLF & @b & $CRLF @@c

    Might be looking for an array of asciiz pointers?

    DIM argv(5) AS DWORD
    argv(0) = VARPTR(Firstsz)
    argv(1) = VARPTR(Secondsz)
    ..
    ..
    glutInit TALLY(@lpCmdLine, " "), VARPTR(argv(0))

    Hi Vladimir!

    At the moment, we can't get glutInit to work no matter how we declare it.

    From glut.h...
    extern void APIENTRY glutInit(int *argcp, char **argv);

    (And we all know char is ASCIIZ...)

    Should be
    DECLARE SUB glutInit LIB "glut32.dll" ALIAS "glutInit" (argcp AS LONG, argv AS ASCIIZ)
    or
    DECLARE SUB glutInit LIB "glut32.dll" ALIAS "glutInit" (argcp AS LONG, argv AS ASCIIZ PTR)

    so...
    glutInit TALLY(@lpCmdLine, " "), @lpCmdLine
    Would be the correct way to call it

    But it keeps crashing
    GLUTEG caused an invalid page fault in module MSVCRT.DLL at 014f:780264b5.

    We are looking into it...

    All good,but one moment.
    glutInit ????

    In GLUT.INC
    '===========================
    DECLARE SUB glutInit LIB "glut32.dll" ALIAS "glutInit" (argcp AS LONG, argv AS ASCIIZ)
    '============== DON'T WORK !!! - SISTEM ERROR 4


    argv must be as string:

    DECLARE SUB glutInit LIB "glut32.dll" ALIAS "glutInit" (argcp AS LONG, argv AS STRING)

    This is good work.
