Firmware 2021 - Test PRINT and PRINT2D cmds

[compsystems]

Hi, the following code works fine from HOME mode, but not from CAS mode.

Note that it uses WAIT cmd, to stop printing, in the hp48 and 50 series it showed HALT at the top, this is important to know that the printing is paused, I think it is also important to place this message, it may be above the la current time
Thanks

PHP Code:

#cas
test_expr2Dprint_CAS():=
BEGIN
    local x,y;
    purge( f, g );
    PRINT(); print; // clear terminal view
    print( "2D printing, Press any key to continue" ); wait;
    print( "\n" );
    print( "Expr1:" );
    print( 'f(x) = x^3 - 2*x^2 + x -1' );
    f(x) := x^3 - 2*x^2 + x -1; wait;
    print( "\n\n" );

    print( "Expr2:" );
    print( 'f(x) | (x=y)' ); wait;
    print( 'x^3 - 2*x^2 + x -1 | (x=y)' ); wait;
    print( f(x) | (x=y) ); wait;
    print( "\n\n" );

    print( "Expr3:" );
    print( 'g(x) = 1/(x+3)' );
    g(x) := 1/(x+3); wait;
    print( "\n\n" );

    print( "Expr4:" );
    print( 'f( g(x) )' ); wait;
    print( 'x^3 - 2*x^2 + x -1 | ( x=g(x) )' ); wait;    
    print( 'x^3 - 2*x^2 + x -1 | ( x = 1/(x+3) )' ); wait;    
    print( f( g(x) ) ); wait;
    print( "\nsimplify:" );
    print( simplify( f(g(x)) ) ); wait;
    print( "\n\n" );

    print( "Expr5:" );
    print( 'g( f(x) )' ); wait;
    print( '1/(x+3) | (x=f(x))' ); wait;
    print( g( f(x) ) ); wait;
    print( "\nsimplify:" );
    print( simplify( g(f(x)) ) ); wait;

    print( "\nDone" );
    return "Done"

end; 


HOME mode
test_expr2Dprint_CAS() [enter] ok, but in the end it returns the source code, this is because the name of the program suppresses the parentheses
