That's precisely what xargs does. For example, ... | xargs commandname will run commandname arg1 arg2 arg3 ...
It'll run commandname program with as many arguments as safely possible without exceeding your system's argument limit. If xargs is fed more lines than your system allows arguments, then it will call commandname more than once.
If you want to limit the number of arugments a program is fed -- one argument per call, for example, use the -n option.

Hello, I was wondering if it were possible to call arguments passed to a script using a variable.
For example:
sh script.sh yes no good bad
x=$#
while
do
echo (last argument, then second last etc until first argument)
let x=($x-1)
done
should print out
bad
good

classes - unique identifiers for catalog-managed objects and component views
SYNOPSIS
#include <Unidraw/classes.h>
DESCRIPTION
Classes for catalog-managed objects, including components, commands, tools, state variables, and transfer functions, must be associated
with mutually-unique class identifiers that can be written onto disk. This allows a creator object to call the appropriate constructor as
part of recreating an object from disk.
Also, there must be a mechanism for creating an appropriate view given a subject; that is, there must be an association between a subject
class and allowable view classes for that subject. This association is established by defining class identifiers for component views.
These identifiers are formed by concatenating the identifier for a given component subject class with an identifier that specifies a ``view
category.'' For example, the class identifier for the PostScript external view of a line component is the concatenation of the identifier
for the line component subject class and POSTSCRIPT_VIEW identifier, which specifies the category of external views for generating Post-
Script. This makes it possible to create an instance of the appropriate PostScript external view subclass given a line component subject.
The class identifiers for the Unidraw base and predefined derived classes are specified in the classes.h include file. Applications that
define new catalog-managed objects or component views should define unique class identifiers in a similar manner. Class identifiers for
catalog-managed objects are simply integers with mnemonic macro definitions, usually the class name in all-uppercase. For example, the
identifier for the LineComp component subject class is
#define LINE_COMP 9030
View class identifiers are specified using the Combine macro, which takes as its first argument the macro definition of the corresponding
component subject identifier; its second argument is an identifier for the view category. The Combine macro itself is then defined with a
mnemonic name. For example, the identifier for the PostScript external view class PSLine (which generates PostScript for the line compo-
nent subject) is defined as
#define PS_LINE Combine(LINE_COMP, POSTSCRIPT_VIEW)
where the POSTSCRIPT_VIEW view category identifier is defined as
#define POSTSCRIPT_VIEW 9103
N.B.: All class identifiers in a given application must be unique.
