18 Pascal 4.0 User’s Guide

To identify the version number given an executable or object ﬁle created by the

Pascal compiler, use the following command.

Compile and Link Sequence

You can compile the ﬁle any.p with the following command-line:

hostname% pc any.p

This command actually invokes the compiler driver, which calls several

programs or passes of the program, each of which processes the program. The

output of each pass is the input to the next one.

After several passes, the object ﬁle any.o is created. An executable ﬁle is then

generated with the default name a.out. Finally, the ﬁle any.o is removed.

pc calls:

• cpp, the C preprocessor or cppas, the preprocessor used when you use the

-xl option

• pc0, the Pascal front end

• The global optimizer if you use the -O option

• cg, the code generator, which generates the relocatable object ﬁle

• pc3, which checks for conﬂicts in symbol names

• ld, the linker, which generates the executable ﬁles using any libraries

necessary to resolve undeﬁned symbols

The above is the default action of pc; some compiler options change what pc

calls.

hostname% mcs -p a.out | grep Pascal
