I'm reading a text file-line by line, I assign values to certain variables.

I want to read a variable in a line after a colon i.e. (: )
Example- if the first line in text file is:

Number of node points:1000

So, 1000 should be assigned to a variable number_nodes but 1000 should be read after the colan(: )

Can anyone advide how to do this?

Thanks,
Christy

Try this example:
Code:
   character line*256      ! contents of line read
   integer*4 n             ! start of bnumber
   integer*4 value         ! value retreived
!
   line = 'Number of node points:1000'
!
   n = index (line,':') + 1
   read (line(n:),*) value
!
   write (*,*) n, value
   end
