#control attribute value
DESCRIPTION
Set various operational modes.
Note: This is part of the general script processing package and
has little use in the ploticus context.
ATTRIBUTES
attribute may be one of:
evalvars
-
-
value should be no to turn off evaluation of variables
and yes to turn it on. Default is yes.
dot_in_varnames
-
-
If value is yes, variable names may contain periods (.).
If value is no, period will be used as a delimiting
character when scanning variable names in the script, and variable
names cannot contain any periods.
The default is normally no.
You might want to set this to yes if you need to accomodate variable
names that contain periods, such as SQL join result column names.
suppressdll
-
-
value should be yes to suppress data-less lines, and no
to show data-less lines. Default is no.
A data-less line is a line
having one or more variables, all of which evaluate to a zero-length value.
Suppressing data-less lines is sometimes useful, for example, when displaying
multi-line entities such as postal addresses.
