macro

References attribute 15 of a file or attribute-defining item. For a file-defining item, the text in this field describes the default attribute name list to include in the update screen. For an attribute-defining item, the text describes the default attribute name list when zooming to another item.

This attribute is used for input exclusively by the Update Processor and has no effect on any other processor, except when there is not a default attribute list on the output-macro attribute of the file-defining item. In this case, the macro attribute dictates the default attributes to be used by the List processor.

Example(s)

A file-defining item with the default attributes to be used by the Update Processor:

ud filename filename

dictionary-code

a

modulo

67

structure

 

retrieval-lock

 

update-lock

 

output-conversion

 

correlative

id100

attribute-type

l

input-conversion

 

macro

name address zip phone (i

output-macro

 

output-conversion

 

description

 

In the example above, since there are no attribute-defining items specified on the output-conversion field, the default attributes used by the List processor are determined by the macro attribute. The i option displays the item-ID of the file along with the specified attributes.

It is possible to have multiple views of the data when the Update Processor is invoked. This is accomplished by having a MultiValue list of attribute-defining items defined on the macro dictionary. To select which view of the data to use, a FlashBASIC subroutine must be called from input-conversion of the file-defining item. In this subroutine, the AQL function is used to pass the position value to the Update Processor.

The example below shows a file-defining item with a MultiValue list of attribute-defining items. A sample FlashBASIC subroutine is included, showing exactly how to select the proper view for the Update Processor.

ud file.name file.name

dictionary-code

a

modulo

structure

 

retrieval-lock

 

update-lock

call select.view

macro

name address zip phone (i

 

name phone comments

 

name phone fax address zip (i

description

 

In the example below, if the user is joe, the view displayed is:

name phone comments

 

u bp select.view

01 subroutine select.view(item)

02 item = access(3)

03 execute ’who’ capturing who

04 user = field(who,’ ’,2)

05 if user = ’joe’ then

06 access(18) = 2

07 end else

08 access(18) = 1

09 end
