container by number The
divide command divides the number in the container or chunk by
number and puts the result into the container.
Dividing by 0 places
INF (for infinity) into the chunk or container. Division is carried out to a precision of up to 19 decimal places.
Note: The container or chunk referred to must contain a number.
If the result is put into a field or the Message box, it is displayed according to the global property
(You can use the
is a operator to see if the container is a number.)
HyperTalk DefinitionA place where you can store and retrieve a value.
There are six types of containers in HyperCard: a variable, a button, a field, the selection, the Message box, and menus.
Additionally, you can refer to a button or field by its part number:
the Message box
bg btn "Names"
card field 1
bkgnd field "Total"
card part 1
last background part
AppleScript DefinitionAn object that contains one or more other objects, known as elements of the container. In a reference, the container specifies where to find an object. You specify containers with the reserved words
You can also use the possesive form (
's) to specify containers. For example, in
the container is
first window's name
first window. The object it contains is a name property.
An expression that evaluates to a number.

i+1 -- (where i is a number)
line 1 of fld "Debits"
Note: Formally, HyperCard distinguishes between factors (simple values) and expressions. The difference between factors and expression matters only if you like to drop parentheses. Most functions take factors as their parameters, which is why
abs of -10 + 2 returns
abs of (-10 + 2) returns
8. In short, always use parentheses to group things the way you want them to evaluate, and you won’t have to worry about the difference between factors and expressions.
