What does this syntax mean....

[ray]

I do not know how to read the following line of code that appear in some MiServer example code:

(frm←Add Form).id←'myform'

When I try executing it I get the error
3:SYNTAX ERROR: Invalid modified assignment, or an attempt was made to change nameclass on assignment
Direction[6] (frm←Add Form).id←'myform'

"CurObj" claims
Form
is
#.HTML.Input.Form (Operator)

However I think Form is supposed to be a Class.

Hi Ray,

I'll use an example outside of MiServer:

      'ns1' ⎕ns ''
      'f' ⎕wc 'form' 

      ⎕cr 'Add'
 r←Add W
 r←ns1  


      (frm←Add f).id←'myform'

      frm
#.ns1

      frm.id
myform

In your tests, is frm already defined?

Regards,

Vince

Thanks Vince. That make sense as far as it goes.

As to my error

First my item "frm" is not already defined.

Within your example, "f" is a name class 9 object.
While my "Form" is already defined by MiServer
(within the scope of the Render method) as an operator

⎕CR'Form'
r←{atts}(method Form)innerhtml
:If 9=⎕NC'atts' ⋄ atts←'action="',atts.Page,'"' ⍝ MildPage calling
:ElseIf 0=⎕NC'atts' ⋄ atts←'' ⋄ :EndIf
atts,←' method="',method,'"'
atts,←('post'≡#.Strings.lc method)/' enctype="multipart/form-data"'
r←('form ',atts)Enclose innerhtml

but I think "Form" should actually be a reference to the class #._HTML.Form

I think my class is not inheriting correctly from the _HTML class.

Thanks
