Hello Folks,

   I haven't used pv-wave for very long, so bear with me if the answer
to my questions seem obvious. In a procedure I am writing, I want to
be able to extra certain data from a .txt file and store that data
into specific variables that I have already in my procedure. The data
within the .txt files are produced through pv-wave so it will always
be the same formatting - so Step1: find the file ( I know how to do
this)
                     Step2: user inputs a number (in my case this is
called the shot number)
                     Step3: check if that number is there
                     Step4:retrieve the data (i would only need the
lines below that shot and above the next shot)
                     Step5:split up the data into specific variables
(I can manage that)
The format of the .txt file looks something like this
shot 12345
h12 54 69 72
h13 47 85 92
.
.
.
shot 12346

Any ideas at all? Sorry if this is all sounds convoluted.

Thanks for any help!
