1 All numeric conversions will continue to accept new data until receiving either the specified
number of digits (ex: three digits for DEC3) or a non-numeric character.
2 To be recognized as part of a number, the minus sign (-) must immediately precede a
numeric character. The minus sign character occurring in non-numeric text is ignored and
any character (including a space) between a minus and a number causes the minus to be
ignored.
3 The hexadecimal formatters are not case-sensitive; “a” through “f” means the same as “A”
through “F”.
4 Indicated hexadecimal and binary formatters ignore all characters, even valid numerics,
until they receive the appropriate prefix ($ for hexadecimal, % for binary). The indicated
formatters can differentiate between text and hexadecimal (ex: ABC would be interpreted
by HEX as a number but IHEX would ignore it unless expressed as $ABC). Likewise, the
binary version can distinguish the decimal number 10 from the binary number %10. A
prefix occurring in non-numeric text is ignored, and any character (including a space)
between a prefix and a number causes the prefix to be ignored. Indicated, signed
formatters require that the minus sign come before the prefix, as in -$1B45.
5 The HEX modifier can be used for Decimal to BCD Conversion. See “Hex to BCD
Conversion” on page 97.
For examples of all conversion formatters and how they process incoming
data, see Appendix C.
