EOM using text "MONTH YEAR"

Hi. It's not particularly elegant, but you can take the components of the incoming date and split them, perform a lookup to swap the text month value for a numeric month value, construct a date based upon the the numeric values you now have (defaulting the day to "01") and then use fn!eom() to get the last day of the month for that date.

Something like this:

load(
  local!listOfMonthsText: {
    "January",
    "February",
    "March",
    "April",
    "May",
    "June",
    "July",
    "August",
    "September",
    "October",
    "November",
    "December"
  },
  local!listOfMonthsInteger: {
    fn!enumerate(12)+1
  },
  local!monthYearComponents: fn!split(ri!monthYear," "),
  local!monthInteger: fn!displayvalue(local!monthYearComponents[1],local!listOfMonthsText,local!listOfMonthsInteger, null),
  fn!eomonth(fn!todate(fn!concat(local!monthInteger, "/01/", local!monthYearComponents[2])),0)
)

load(
local!listOfMonths: {
"January",
"February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December"
},
local!month: cast(
typeof(
1
),
wherecontains(
stripwith(
stripwith(
"February 2019",
right(
"February 2019",
4
)
),
" "
),
local!listOfMonths
)
),
eomonth(
date(
right(
"February 2019",
4
),
tointeger(
local!month
),
1
),
0
)
)
