Compressing Programs

The space occupied by a deleted version of a program remains part of the code file.

The space occupied by an associated symbol table remains part of the symbol table

file. You can use SCUP to reclaim the space left by the deleted programs and symbol

tables. SCUP rewrites the code and symbol table files to pack the programs together.

SCUP preserves the access flag of the program, but renumbers the program versions

starting with version 1.

Figure 1-4 is an example of a code file and a symbol table file before and after

compression.
