When To Use HP Link Editor/XL
Most HP compilers (for example, HP COBOL II) let you compile, link, and
execute a program in one step. Or you can compile and link in one step.
In these cases, you do not execute HP Link Editor/XL directly to perform
the linking function. It is executed automatically.
There are occasions, however, when you may want to compile and link a
program yourself in separate steps. You may need to directly execute HP
Link Editor/XL when:
* You need to create an executable program file (the executable form
of a program) which includes several different modules that have
been compiled separately.
* You need to change one or more of the default parameters
associated with the program. For example, you may need to change
the execution stack size.
* You want to use one or more library routines in your program. HP
Link Editor/XL creates and maintains two kinds of libraries -
relocatable libraries and executable libraries. Routines in
relocatable libraries are in their compiled format. Routines in
executable libraries are in executable form. Libraries minimize
duplication of programming effort while promoting consistency and
standardization within a programming organization. They also help
to produce easily-maintained programs.
