4. Select Object->Card Script and enter the following to handle enabling the buttons.

switch

case v <= 0

put v into fld "Field1"

end switch

 

put field "Field1" into x

add 1 to x

enableButtons x

 

put field "Field1" into x

subtract 1 from x

enableButtons x

 

if numToChar(k) is among the items of "1,2,3,4,5,6,7,8,9,0" then

if (numToChar(k) + the text of me) <= 10 then

pass rawKeyDown

end if

 

Switch back to the form, and enter run mode to execute.

Normally a function can't call other except something global or something defined in function (local), or for member functions in Group object, they can call other members public or private at same level or deeper but then only the public members. Using Call Local we call functions like function's part. When an event service function called (by event), interpreter provide the same name as the module's name, where form declared, so this call is a "local call". So a second local call inside event service function,also provide same name. So global local1 called as local, so code executed as part of CheckIt (but without same "current" stack, and other specific to execution object properties). Modules, functions, threads, events are all executed on "execution objects" which carries the execution code.

 

\\ this is global, but call as local in events, which means with local visibility for identifiers

\\ so thispos and this$ has to exist in caller 's context

Checkit

 

 

=={{header|Maple}}==

For this problem, you will need to open up Maple, go to the Components tab on the left, and insert a Text Area, and 2 Buttons. By right clicking each button, and clicking Component Properties, change one to Increase, and the other to Decrease. Then, click on 'Edit Content Changed Action". In the one labeled increase, type:

 

Increase();

 

In the one labeled Decrease, type:

 

Decrease();

 

Then, by clicking the 2 gears and opening up the start-up commands, enter this:

macro(SP=DocumentTools:-SetProperty, GP=DocumentTools:-GetProperty);

with(Maplets[Elements]):

end if;

end proc;
