Chapter 3 STRATEGIES FOR USING THE SEGMENTER
When we discuss strategies for using the Segmenter, we have two major
areas of concern:
* Managing libraries so that heavily-used code can be shared among
programmers.
* Controlling segmentation or altering the contents of a segment.
A very strong caution applies whether you will use the Segmenter heavily
or just occasionally for either of these purposes: keep either your
source code or your USLs. If you have not done so and then need to alter
code or change your storage strategy, you will have to rewrite your code.
Attempting to reconstruct the code as it existed before is difficult and
time-consuming.
Many experienced Segmenter users have found that saving source code
rather than USLs provides more flexibility, since you can then change
code or alter storage arrangements. If you have saved only the USL, you
are limited to changes in storage arrangements, since you cannot alter
the code in a USL. Keeping a copy of all your source code requires a
relatively small investment in disc space or in magnetic tapes for a
significant return in efficiency.
