Yes, using
Shell "cd /another/directory"
spawns a new process (the shell) which changes its directory (using the cd
built-in) to /another/directory and then dies. Since the CWD is local to a
process, this does nothing with your Gambas process.

There is no concept of a current working directory in Gambas, as stated
here[0]. If you want to change the CWD of your process nevertheless, I
guess you can use Extern[1] and access the chdir() function in the C
library but I don't know what consequences that will have.
A cleaner solution is to use absolute paths throughout. The CWD from process
startup time is found in Application.Dir. If you didn't call chdir() since
then, it will give you your CWD and any relative path sRel can be made into
an absolute path via
Application.Dir &/ sRel
