RE: calculate first monday or working day

I would probably use a data structure to set the inputDate to the 1st of the
month and loop adding one day at a time until #dayOfWeek returned the number
2.

d #dayOfWeek      pr             1s 0                           
d inputDate                       d   const options( *nopass )  



p #dayOfWeek      b                   export                                
                                                                            
d #dayOfWeek      pi             1s 0                                       
d inputDate                       d   const options( *nopass )              
                                                                            
d dayOfWeek       s              5i 0

Anyone have any code or formula that will calculate the first monday or
first working day of the month for any given year?

TIA,

Frank
