What do you mean by "the routines fail"?  Is it that they don't get
compiled correctly?  Or they don't receive correct arguments from
Pascal?  I used several C routines from Pascal programs and never had
any problem.

BUT... using ``system("cd xxx")'' is bound to fail (i.e., return without
any observable effect) when called either from C or from Pascal.  The
reason is that "system" spawns a shell to execute the command.  The
shell will change its **own** directory but **not the one of its parent
process** (the Pascal program).

You'd better re-read your Unix manual...
