Example from the web:

procedure SetFormat;

static

    chr2    :w.CHARRANGE;
    cf      :w.CHARFORMAT;

    push    (eax);
    
    w.SendMessage(hwnd, w.EM_EXGETSEL,0, &chr);
    w.SendMessage(hwnd, w.EM_HIDESELECTION, true,0);
    mov (0, chr2.cpMin);
    mov (-1,chr2.cpMax);
    w.SendMessage(hwnd, w.EM_EXSETSEL,0,&chr2);
    mov (@size(cf), cf.cbSize);
    mov (w.CFM_CHARSET | w.CFM_FACE | w.CFM_SIZE | w.CFM_COLOR, cf.dwMask);
    mov (logfont.lfCharSet, al);

    mov (logfont.lfPitchAndFamily, al);

    mov (logfont.lfHeight, eax);
    neg (eax);
    mov (15,ecx);
    mul     (ecx);

    mov (rgb, cf.crTextColor);
    w.SendMessage(hwnd, w.EM_SETCHARFORMAT, w.SCF_SELECTION,&cf);

Language features

Feature	Supported	Example
Macros	✓	// _SortCases_ // // This routine does a bubble sort on an array // of _caseRecord_ objects. It sorts in ascending // order using the "value" field as the key. // // This is a good old fashioned bubble sort which // turns out to be very efficient because: // // (1) The list of cases is usually quite small, and // (2) The data is usually already sorted (or mostly sorted). macro _SortCases_( ary, size ):i, bnd, didswap, temp; ?bnd := size - 1; ?didswap := true; #while( didswap ) ?didswap := false; ?i := 0; #while( i < bnd ) #if( ary[i].value > ary[i+1].value ) ?temp := ary[i]; ?ary[i] := ary[i+1]; ?ary[i+1] := temp; ?didswap := true; #endif ?i := i + 1; #endwhile ?bnd := bnd - 1; #endwhile; endmacro;
