[pdftex] Section/Subsection Labeling

[John S. Dey]

Hello Friends:

I have a legacy document that gets updated printed every couple 
of  years.  I have converted to LATEX.  The sections in the document are 
labeled 100, 200, etc and the subsections as 101, 102, etc.  I have 
attempted to change the default to produce the documents section/subsection 
numbering scheme without success.  Is there a patient person, that could 
provide me with the preamble statements that would change the 
default.  Thanks in advance for your assistance.
