Hi Soumya,
Depends on your familiarity with Python really.  If you don’t know Python well then it might be easier to parse the reply log.  If you have some familiarity with Python then you would use the Python equivalents of the angle/distance commands to get the values and write them to a file (runCommand never returns a value itself).
In Python, you could use runCommand to select the atoms you want to measure and then:

Outside the loop
from Midas import distance, angle

Inside the loop, either
d = distance()
… write the distance to a file...

or
a = angle()
… write the angle to a file...

Hello,

 I have just modified the loop script available here (http://www.rbvi.ucsf.edu/chimera/docs/ProgrammersGuide/basicPrimer.html) 
to measure certain angles and distances. I just want to know if there is a way to export the individual values of angles and distances to a file other than parsing from the reply-log. Thank you.

Best,
