This function returns a character result representing the numeric
value edited according to the edit code. In general, the rules for
the numeric value and edit code are identical to those for editing
numeric values in output specifications. The third parameter is optional,
and if specified, must be one of:
Indicates that asterisk protection is to be used. This means
that leading zeros are replaced with asterisks in the returned value.
For example, %EDITC(-0012.5 : 'K' : *ASTFILL) returns '***12.5-'.
Indicates that a floating currency symbol is to be used. The
actual symbol will be the one specified on the control specification
in the CURSYM keyword, or the default, '$'. When *CURSYM is specified,
the currency symbol is placed in the the result just before the first
significant digit. For example, %EDITC(0012.5 : 'K' : *CURSYM) returns ' $12.5 '.
Indicates that floating currency is to be used with the provided
currency symbol. It must be a 1-byte character constant (literal,
named constant or expression that can be evaluated at compile time).
For example, %EDITC(0012.5 : 'K' : 'X') returns ' X12.5 '.
The result of %EDITC is always the same length, and may contain
leading and trailing blanks. For example, %EDITC(NUM : 'A' : '$')
might return '$1,234.56CR' for one value of NUM and ' $4.56 '
for another value.
Float expressions are not allowed in the first parameter (you can
use %DEC to convert a float to an editable format). In the second
parameter, the edit code is specified as a character constant; supported
edit codes are: 'A' - 'D', 'J' - 'Q', 'X' - 'Z', '1' - '9'. The constant
can be a literal, named constant or an expression whose value can
be determined at compile time.
