Dear Anthony:
Whoa!!! Hold on, big fella. Let's do a sanity check here. In any just
and decent world, an ordinary dash (-) in ASCII should map to the same
graphic in EBCDIC. I think you were using the wrong table.
The dash in ASCII is 0x2D, as shown in Table 4: 7-bit ASCII Definitions.
Using Table 2b -- 8-bit ASCII --> EBCDIC, you see that 0x2D maps to 0x60
in EBCDIC, which Table 3: EBCDIC Definitions shows to be the dash, as
expected.
Further, you added "No wonder X12 likes to express money as an absolute
value with a separate sign indicator. If you try to send a negative
number from ASCII to EBCDIC, you won't get the sign character through
conversion." Actually, X12 numeric elements do include the minus sign,
or dash, for negative numbers. Maybe you're thinking of the COBOL SIGN
SEPARATE thingy.
