I have a form level method:
method TakeString(var Hint string)
endmothod

I attempt to call it from a uiobjects mouseenter method like this

TakeString("Hello There")

I get the syntax error "parameter mismatch on the TakeString statement.

According to the help files, I can pass a string by value.

I know I can do the following

var Passit string endvar
Passit = "Hello There"
TakeString(Passit)But I'd really like to pass the literal.

I'm sure I'm missing something obvious.

TIA,
Waterstone

Just an guess but the word var means variable you are passing an constant. ( var means it can return an value; you can't return an value to an constant.)

Try using TakeString(String("Hello There"))
or removing the var in the method defination.

Tim,

Thanks for the suggestion. While the suggestion did not work because the called method cannot have a string literal as an argument, your post prompted me to use constants to define the values I wanted to pass, making the code much neater.

method ShowHints(const Hint String)

message(Hint)
HintText = Hint
HintBox.visible = true

endMethod

Then called it with predefined constants

ShowHint(Report01) where Report01 is a constant declared at the form level.

Thanks Again,
Stephen

You can also simply remove "var":

method TakeString(Hint string)

Bye!
