Thank you, Paul and Ben.

this is what I want,
ssh myhost '. /etc/profile; echo $MYDIR'  
It works good, thank you. 

Problem was not in standard command "echo". It was in my program (see prev. 
message).
This one works
.......
  if ((dir = getenv("MYDIR")) != NULL) 
.......
But this not
.......
  if ((dir = getenv("PATH")) != NULL) 
.......

It seems that there is another place (not /etc/profile), where environments 
PATH etc. are stored. But where?
Can I put my environment  there and do not run . /etc/profile like this:
ssh myhost '. /etc/profile;  ............'

Thank you so much!

p.s. sorry, my English is worst.
