2007-07-19 converting borland pascal (turbo pascal under ms-dos) into gnu-pascal

the readln() and read() works kind of different. the ms-dos version is kind of smarter.

to make borland specific statements compatible to the gnu-pascal compiler, gpc, add '--borland-pascal':

gpc  -Wall --borland-pascal -o MIHDEEP2 MIHDEEP2.pas

haven't figured out how to use Dos and Crt units under linux from /usr/lib/gcc/x86_64-linux-gnu/3.4.6/units/

sample programs check directory pascal/ of repositary test.
