where put(B.MONYYYY,MONYY7.)=put(a.default_mth+1,MONYY7.)

in this command does 1 means add one month?

The MONYY format is for date values. SAS date values are counts of days.

You've got already the answer that +1 adds one day to a SAS date value.

The comparison then first writes the SAS date values as a string using a format that prints month and year. So what this selection logic obviously is doing is to only select rows where both dates are within the same month.

Another way to write this expression would be:

where intck('month',B.MONYYYY, a.default_mth+1)=0
