Requests master help to answer, thanks ~


QTEST.lsp code:
(DCL_LOADPROJECT "ODLS_006.odcl" T)
(dcl_FORM_SHOW ODLS_006_TS)

(if (/= sText "")
(dcl_Control_SetText ODLS_006_TS_TBX sText)
)

;;;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(defun GET_TEXT ( / EN EN_TXT)
(SETQ EN (CAR (ENTSEL "\n SELECT TEXT :")))
(SETQ EN_TXT (CDR (ASSOC 1 (ENTGET EN))))
EN_TXT
)

;;;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(defun PUT_TEXT ( EN_TXT / EN OLD_TS)
(SETQ EN (CAR (ENTSEL "\n SELECT TEXT :")))
(setq endata  (entget en))
(setq oldlist (assoc 1 endata))

Welcome to the forum.

Looks like you need an initialize event ..
and the OnUpdate code doesn't look correct.
I'll have a look after I have my morning coffee.

I've made some changes.
// odcl
1) removed ALL the Event notification from the Textbox in the ODCL.
2) added an onInitialize Event to set the initial values when the form loads.
3) Changed Textbox LimitText property from 1 to 100
4) Changed Textbox ReturnAsTab property to true.

// lsp

added a command line defun c:qtest (...
added c:ODLS_006_TS_OnInitialize (...
changed sText variable name to global:sText
changed test logic to test for nil global:sText value.
changed the local function names to _GET_TEXT and _PUT_TEXT ; ( personal preference only)
forced the local functions to the defined locally, NOT globally.
