OK. With what I showed you in post #2 in this thread, what other information do you need to complete this task on your own? I thought I gave you everything you needed there for cases where the data fields do not overflow the specified field widths (or you want to truncate input data if it is too long to fit the output field) whether you want left-justified or right-justified output.

Australia,1234,engineer
Africa,12399999,doctor

role column will start from 31-35.
You can use Don's example to cobble up something...and yes you can change the printf specifier so it'll take variable length fields instead of fixed length ones that may exceed the maximum specified field width.

Hint...lookup the "%.*s" printf specification.
