<B>DEFDBL Define Variable(s) as Double Precision</B>
|
|
|
|
<B>DEFDBL</B> <U>letter</U>[-<U>letter</U>] [,<U>letter</U> [-<U>letter</U>]]...
|
|
|
|
Declares one or more variables to be double precision.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
<B>Notes:</B> All variable names beginning with any of the specified
|
|
letters (case-insensitive) will be double precision,
|
|
unless a type-identifier character (%, !, or $) is used to
|
|
override the DEFDBL declaration.
|
|
|
|
The DEFDBL declaration must be read by the compiler before
|
|
any statements in which the declared variables are
|
|
assigned or used. The compiler reads from beginning to
|
|
end, without regard for execution path.
|
|
|
|
You cannot avoid a DEFDBL declaration by direction the
|
|
execution path around it.
|
|
|
|
DEFDBL statements do not affect symbolic constants.
