Converting a text expression to date |
SYNTAX
todate(text_expression)
This function converts text_expression into a date (i4/dn datatype). It is a convenient helper method that permits date comparisons of dates held in strings against dates in standard date fields in the i4/dn format. Previously it was often necessary to convert the string to an i4/dn to get reliable results.
The function returns a numeric value of type i4/dn
EXAMPLE
!define TESTDATE "01/01/2021"
!define TESTDATE_PLUS_ONE "02/01/2021"
!temp tdate,,i4/dn
tdate = TESTDATE
if (tdate = todate(TESTDATE)) {
info "We can compare the dates using the todate() helper function"
}
if (tdate != TESTDATE) {
info "While directly the date and string can't be compared"
}
if (tdate < todate(TESTDATE_PLUS_ONE)) {
info "tdate is previous to " + TESTDATE_PLUS_ONE
}
