Hi All,

My first time here! icon_smile.gif

I'm a student seconded to a Large bank in the UK as part of my course and I'm learning COBOL in my spare time (GNU COBOL). As a project, I'm writing a simple airline booking program and have got quite far. The help I need is as follows:

If I have a 100 seater aeroplane setup as 4 rows of 25 seats, I want to be able to read the seat numbers in from a file and display where they are booked on this 4 x 25 grid as follows:

row1: xxxxxxxxx*xxxxx*xxxxxxx*x
row2: xxxxxxxxxxxxxxxxxxxxxxxxx
row3: xxxxxxxxxxxxxxxx**xxxxxxx
row4: xxxxxxxxxx*xxxxxxxxxxxxx*

In this example row 1 shows seats 10, 16 and 24 as booked
row 3 - seats 67 & 68 are booked
row 4 - seats 86 & 100 are booked (x's are empty seats)

Can anyone help with a simple way of doing this? I've been at this for weeks with no real success.

Thanks in advance,

Darren

Funny sort of airplane! Do you mean 25 rows of 4 seats per row?


In any event, SergeyKen is correct - you are not an expert so really should be in the Beginners Forum.
