Is there a function to add the months to a date, for eg: 24-02-99 + 6 months = 24-08-99.
The date is normally in the format 19990224 and you can then use
variable+4(2) = variable+4(2) + 6.
Otherwise you can use the function RP_CALC_DATE_IN_INTERVAL.
call function 'RP_CALC_DATE_IN_INTERVAL'
date = datum "variable with you date before adding 6 month
days = nul "variable with the value of 0
months = halfyear "Variable with the value 6
* SIGNUM = '+'
years = nul
calc_date = datum "the variable will now hold your new date
others = 1.
