DETACH (DET, DTH)
DETACH (DET, DTH)
The DETACH; command moves text from an alphanumeric (EDIT; A, EDIT; K or EDIT; W)
data item into a second data item of the same edit type.
Following execution of the DETACH; command, the System Data item GLB.LENGTH
contains the length of the text selected from the first data item.
Position and Delimiter
The text to be moved is defined by a starting position, and by the occurrence of a delimiter.
Starting Position
If the starting position is invalid, no move will take place and the second data item will
contain spaces. The default starting position is the first character.
If a data item is used to specify a starting position, it will be updated to the position of the
first non-delimiter character (following the delimiter) in the first data item value.
Delimiter
The default delimiter is a space. Multiple consecutive occurrences of the delimiter are
treated as a single occurrence. The delimiter is not included in the move.
If the specified delimiter is not found, the contents of the first data item starting from the
specified starting position are moved to the second data item The contents are truncated if
the second data item is too small.
Truncation of Data
The maximum length moved by a DETACH; command is 2000 characters. This is
equivalent to 1000 Kanji (EDIT; K) characters.
The text selected by the DETACH; command may be truncated if the second data item is
too small.
If you move a mixed alphanumeric and Hankaku-Katakana value into an EDIT; W data
item, the value is moved character by character, and is truncated to the length of the
data item. However, if you move a mixed alphanumeric and Hankaku-Katakana value into
an EDIT; A data item, the value is moved byte by byte and is truncated to the length of the
data item. If the truncation occurs after the first byte of a double-byte Hankaku-Katakana
character, this will result in an invalid character.
Note: EDIT; W data items are not implemented in LDA.
