Hello, is there a way that dynamic arrays can be created (using schemata) which are GLOBAL, i.e. not accessible in the sole main program, but also in all functions and procedures included in it? For instance this little piece of code gives me this error: espon.pas: In procedure `Merce': espon.pas:50: undeclared identifier `Vett' (first use in this routine) espon.pas:50: (Each undeclared identifier is reported only once espon.pas:50: for each routine it appears in.) espon.pas:50: subscripted object is not an array or string the code follows: program skifo; type TVecDob (Size: Integer) = array [ 1 .. Size ] of double; PVecDouble = ^TVecDob; Function Power ( base: real; espon: integer ): double; var i, j: integer; buff: real; begin buff := base; for i :=1 to espon - 1 do begin buff := buff * base; end; result := buff; end; Procedure merce; var i,j: integer; begin for i := 1 to 10 do begin writeln (' vett ', i, '=', vett [i] ); end; end; var nelem, i, j : integer; begin nelem := 10; var vett: TVecDob ( nelem ); for i := 1 to 10 do begin vett [i] := 1+0.1*i; end; merce; end. Thank you very much Silvio
