SYMPTOM(s):
NUM-ENTRIES does not work when field contains ?
CAUSE:
According to Progress help:
The question mark is a special character that represents the unknown value. Progress treats a quoted question mark ("?") in a procedure or an input field as a question mark character. It treats an unquoted question mark (?) in a procedure or an input field as an unknown value.
FIX:
Enter "?" in the input field or assign the screen-value of the field before using num-entries.
Example:
define variable x as character.
update x.
/* it treats ? as unknown */
message "num-entries is " num-entries(x) view-as alert-box.
/* if ? is not in between quotes, assign its screen-value */
X = X:SCREEN-VALUE.
message "num-entries is " num-entries(x) view-as alert-box.
