Name: HCAddressing

Type: property

Syntax: set the HCAddressing of <stack> to {true | false}

Summary:

Determines whether <grouped control|grouped fields> and

<card control|card buttons> are assumed if the <field> or

<button|button's> <domain> is not specified.

Associations: stack

Introduced: 1.0

OS: mac, windows, linux, ios, android

Platforms: desktop, server, mobile

Example:

set the HCAddressing of stack nextImport to true

Value (bool):

The <HCAddressing> of a <stack> is true or false.

By default, the <HCAddressing> of <stacks> you create in LiveCode is set

to false.

Description:

Use the <HCAddressing> <property> for compatibility with <HyperCard>.

When you open a HyperCard stack and convert it to a LiveCode stack, the

new stack's <HCAddressing> <property> is set to true.

If the <HCAddressing> <property> is set to true,

<expression|expressions> in the <stack|stack's> <script|scripts> that

refer to <field|fields> without specifying <card> or <background> are

assumed to refer to <grouped control|grouped controls>, and

<expression|expressions> that refer to other control types are assumed

to refer to <card control|card controls>. For example, the number of

fields reports the number of grouped fields, while button 5 refers to

the fifth card button. Also, the <value|values> reported by the <long>

or <abbreviated> <name> and <ID> <properties> of <controls> include

"card" or "background" as the first word, depending on whether the

<control(keyword)> is part of a <group>.

If the <HCAddressing> <property> is false, <expression|expressions> that

refer to <field|fields> or <buttons> without specifying <card> or

<background> are assumed to refer to all <field|fields> or <buttons>.

For example, the number of fields reports the total number of card and

<background> <field|fields>, and button 5 refers to the fifth button.

If a stack's <HCAddressing> <property> is true, the <style> <property>

of a <button(keyword)> whose style is "menu" reports "popup" instead.

This is because HyperCard uses a style setting of "popup" to designate

popup menus.
