optional variables in User Defined Function - UDF

[Mike Wilson]

I got one hit with search for "optional variable". Didn't help.
I'm trying to add an optional variable to a UDF. I tried the format that is shown for standard system functions shown in red, but no joy. Can you do this for UDF's and if so how? Thanks

FUNCTION dlg_alert_box AS V (input_msg as C, box_pos as C [COLOR="Red"][,open_time as n][/COLOR])
	
'if "open_time" !$ variables_enum(local_variables())
	dim open_time as n=2.2
'end if

dim dlg_body as C
dim mdlg as C="ENTRY ERROR"
vlen=len(alltrim(input_msg))+8
box_pos=left(box_pos,1)+","+word(box_pos,2,"-")
input_msg=space(5)+input_msg

z1=<<%dg1%
{position=%dg1%

z2=<<%dg2%
}{background=yellow}{font=arial,10,b}{nocaption}
{lf};
{region}
{text=%dg2%

z3=<<%dg3%
,1input_msg}
{lf};
{endregion};
%dg3%

ui_beep(UI_ASTERISK_BEEP)

dlgF=z1+box_pos+z2+vlen+z3
'msgbox(dlgF)
ui_modeless_dlg_box(mdlg,dlgF)

xbasic_wait_for_idle()
sleep(open_time)
ui_modeless_dlg_close(mdlg)

END FUNCTION

dlg_alert_box("You are not authorized to edit this document","6-2")

Hard to find in the help but it appears in this section.

If you open_time = 0 I don't think you need the as N.

Thanks Al, and Stan. Stan, from where did you get that page? I couldn't find it to begin with, and now even knowing it exists, I can't find it in the Help files. Where did it come from and how did you get it? It's not under User Defined Functions!

Stan's link (appears in this section) points to the online help file. Then click show all to see the index on the left..

Screenshot of search. Also found searching for optional parameter.

Al,
I get that, but that is working BACKWARDS from the end. I want to know how he got that page beginning with opening the Help files and moving FORWARD to get to the page he referenced in his link. Again, it is not accessible from the listed topics under User Defined Function index list. He got there somehow. My question is how, so I can find it in the future when needed.


LATER.
Thank's Stan...
OK, I see.... The User Defined Function link in the SEARCH tab is different than the User Defined Function in the Index tab. Gee... that's clear and intuitive. I thought they were always the same. Doppy me. ( I can't get to the Web Help files. It locks up my IE).
