For example, a six digit - -- number has the format: - - -- 0d dd dd ds - - -- The sign digit has the possible values - - -- 16#0A# non-standard plus sign - -- 16#0B# non-standard minus sign - -- 16#0C# standard plus sign - -- 16#0D# standard minus sign - -- 16#0E# non-standard plus sign - -- 16#0F# standard unsigned sign - - -- The non-standard signs are recognized on input, but never generated - -- for output numbers. The 16#0F# distinguishes unsigned numbers from - -- signed positive numbers, but is treated as positive for computational - -- purposes. This format provides distinguished positive and negative - -- zero values, which behave the same in all operations. - - type Packed_Format is (U, S); - - Packed_Unsigned : constant Packed_Format := U; - Packed_Signed : constant Packed_Format := S; - - type Packed_Representation_Type is (IBM); - -- Indicator for format used for packed decimal - - Packed_Representation : constant Packed_Representation_Type := IBM; - -- This version of the spec uses IBM internal format, as described above - - ----------------------------- - -- Display Decimal Formats -- - ----------------------------- - - -- Display numbers are stored in standard ASCII format, as ASCII strings. - -- For the embedded signs, the following codes are used: - - -- 0-9 positive: 16#30# .. 16#39# (i.e. natural ASCII digit code) - -- 0-9 negative: 16#20# .. 16#29# (ASCII digit code - 16#10#) - - type Display_Format is (U, LS, TS, LN, TN); - - Unsigned : constant Display_Format := U; - Leading_Separate : constant Display_Format := LS; - Trailing_Separate : constant Display_Format := TS; - Leading_Nonseparate : constant Display_Format := LN; - Trailing_Nonseparate : constant Display_Format := TN; - - subtype COBOL_Digits is COBOL_Character range '0' ..
