Fortunately a situation I have never encountered, nor hope to.
I believe this may be yet another example of an interviewer talking out of his/her a**e
Are we to understand that the execution cycle in days is equal to the number of steps involved. |

Using scheduling software it is possible to include differing parts of a job given different days/schids/situations.
That is the only way that I can think of get around this, unless you write a small REXX or program to issue different return codes for whatever day of the week it is. |

since it' s raining here is a rexx snippet to compute an offset or an index into a cycle
| Code: |
cystar cycle starting date
cydays number of days in the cycle
cyoffs 0 to retur an offset 1 to return an index |
I' ll let somebody else explain the logic
| Code: |
cystar = date("S")
cystar = 20090720
cydays = 10
cydays = 7
cyoffs = 0
cyoffs = 1
say cycle(date("S"), cystar, cydays, cyoffs)
exit
cycle: procedure
parse arg cycurr, cystar, cydays, cyoffs
return ( date("B",cycurr,"S") - date("B",cystar,"S") ) // cydays + cyoffs

anyway that' what schedulers are built for ...
manage execution cycles ...
write a job for each step and create the appropriate schedule definition |

Aaru - have you not ever seen any of my responses to people who want to use SLEEP 
Although, it would work. Just imagine hogging an initiator for a whole week to process just one job  The type of response it needs really.
I'd just love to interview the a***hole that asked that one in an interview. |

but for a weekly cycle, based on the day of the week a simple
date("B") // 7 will return 0 for monday ... 6 for sunday
see the rexx manual for the date function |

You should have asked the interviewer -- Should the step repeat after one week? 1st and 8th step should be executed on 8th day or just the 8th step? and for a year should I code "365 steps"..  |

Hi,
you can always create a number of jobs, then schedule each job on the designated day or as already mentioned, most scheduling tools will allow you to place code around each step of the job and schedule it according to it's criteria.
