Combine column in text filesStarted by:hanin, 06/05/2008 03:09AM
Hello,

is there any way in IRAF to combine
columns in text files? For example:
file1(colA,colB) and file2(colC,colD)
--> file3(colA,colB,colC,colD).

Thank you.

Hi,

in a cl script I am trying to read in a
string of numbers, e.g. "12,15,19". Is
there an easy way to split this string
at the delimiter "," into individual

integers?
