Thank you all for the responses.
I do have code after the inner loop. I should have mentioned they are simple for loops.
But my project is generating table markup for a year calendar.
The outer loop produces the rows, while the inner loop produces the cells in each row,
As I thought of this, it occurred to me that breaking out of the inner loop will produce a
row with less than 7 cells. So I actually shouldn't do it here.
I am having difficulty getting the month day numbers to fall on the correct week days.
I would post what I have on my web site, but alas, my site doesn't have a hosting service
at this time. (any suggestions for a reasonably priced, reliable, unix based hosting service
in the US?)
The process of contemplating and posting about issues is a process of clarifying
the issues so solutions tend to emerge regardless of the responses. The responses
are most often helpful.
Thank you again for time and attention
