Copying Programs

You can copy programs from one object file to another. SCUP copies the programs

and assigns version numbers in the order you specify, thus giving you control over the

priority assigned to versions of a program.

If the program to be copied has an associated symbol table, SCUP copies the symbol

table to the destination symbol table file.

Deleting Programs

You can delete programs from the object files. SCUP deletes programs by removing

the entry for the program in the directory file.

When you delete a program, SCUP does not alter the code file until the file is

compressed; thus, a program that is currently in use by a TCP can be deleted while the

program processing continues. Any subsequent reference to the deleted program

either accesses another version of the program or fails if the deleted version was the

last one. If the deleted program has an associated symbol table, the entry for the table

is deleted from the directory file, but the symbol table file is not altered until the file is

compressed.

An example of code and directory files with deleted programs is shown in Figure 1-3.
