Iso Option File TTfont

I have an Iso option file containing TEXTPOSITION

TEXTPOSITION 'Project Title' AT X457 Y63 CHAR H 2

Is there anyway I can also justify this text

TEXTPOSITION 'Project Title' AT X457 Y63 CHAR H 2 JUST LEFT doesn't work... Does anybody know the correct syntax please

Position based X Y Only
there is no justification syntax

define function !!aligniso (!inputtext is string, !x is real, !y is real, !charheig is real, !alignparam is string)
    !align = !alignparam.upcase()
    !z = !charheig * 0.7
    !l = !inputtext.length()
    if !align eq |R| then
        !x1 = !x -!l * !z
    elseif !align eq |C| then
        !x1 = !x - ( !l / 2 ) * !z
    else
        !x1 = !x
    endif
    !output = |TextPosition '$!inputtext' X $!x1 Y $!y charheight $!charheig|
   $!output
endfunction

In Option file use !!aligniso ('Project Title', 457,63,2, 'r'), instead of TEXTPOSITION 'Project Title' AT X457 Y63 CHAR H 2

'r' - for right just

'c' - for center just

and '' - for left just
