v Two adjacent field delimiters (no data in between).<br />
v A field delimiter followed by a record delimiter (no data in between), an<br />
empty string.<br />
v A field of all blanks<br />
If the field is null, the following is true:<br />
v If the record’s output field is not nullable and the import is a null field,<br />
the record is not to be copied, and an error is signaled.<br />
Delimiters<br />
v A delimiter cannot be a blank<br />
v A string delimiter cannot be the same as a field delimiter, record<br />
delimiter, date separator, or time separator.<br />
v A string delimiter can enclose all non-numeric fields (character, date,<br />
time, and so forth). The string delimiter character should not be<br />
contained within the character string.<br />
v A field delimiter and a record delimiter can be the same character.<br />
v The defaults for delimiters are as follows:<br />
– String is: ″ Double quote.<br />
– Field is: , Comma.<br />
– Decimal point is: . Period.<br />
– Record is *EOR End of record.<br />
v If the data type of the from is CHARACTER, OPEN, EITHER, or ONLY,<br />
all double byte data must be contained within string delimiters or shift<br />
characters (for OPEN, EITHER, ONLY data type).<br />
Numeric Field<br />
v Numeric fields can be imported in decimal or exponential form.<br />
v Data to the right of the decimal point may be truncated depending on<br />
the output data format.<br />
v Decimal points are either a period or a comma (command option).<br />
v Signed numeric fields are supported, + or -.<br />
Character or Varcharacter Fields<br />
v Fields too large to fit in the output fields are truncated (right). The<br />
system sends a diagnostic message.<br />
v An empty string is defined as two string delimiters with no data<br />
between them.<br />
v For the system to recognize a character as a starting string delimiter, it<br />
must be the first non-blank character in the field. For example, ’abc’ with<br />
’ as the delimiter is the same as abc.<br />
v Data after an ending string delimiter and before a field or record<br />
delimiter is discarded.<br />
IGC or VarIGC Fields<br />
v The system copies data from the from-file to the to-file. If any of the<br />
data is not valid, the system generates a mapping error.<br />
v Data located between the Shift Out and Shift In characters is treated as<br />
double-byte data. This data is also not parsed for delimiters. The Shift<br />
characters in this case become ″string delimiters″.<br />
Graphic, VarGraphic Fields<br />
The system copies the data from the from-file to the to-file.
