+@cmd{DELETE VARIABLES} should not used after defining transformations

@cmd{VECTOR} allows a group of variables to be accessed as if they
were consecutive members of an array with a vector(index) notation.
-To make a vector out of a set of existing variables, specify a name for
-the vector followed by an equals sign (@samp{=}) and the variables that
-belong in the vector.
+To make a vector out of a set of existing variables, specify a name
+for the vector followed by an equals sign (@samp{=}) and the variables
+to put in the vector. All the variables in the vector must be the same
+type. String variables in a vector must all have the same width.
To make a vector and create variables at the same time, specify one or
more vector names followed by a count in parentheses. This will cause
variables named @code{@var{vec}1} through @code{@var{vec}@var{count}}
-to be created as numeric variables with print and write format F8.2.
-Variable names including numeric suffixes may not exceed 64 characters
-in length, and none of the variables may exist prior to @cmd{VECTOR}.

Vectors created with @cmd{VECTOR} disappear after any procedure or
procedure-like command is executed. The variables contained in the
Variables within a vector may be referenced in expressions using
@code{vector(index)} syntax.
