APPEND
Concatenate two data blocks
REAL Input-real-default=0.0. Real value in the next record.
REALD Input-complex-default=0.D0. Complex value in the next record.
CMPX Input-complex-default=(0.0,0.0). Complex value in the next record.
CMPXD Input-complex double precision-default=(0.D0,0.D0). Complex double
precision value in the next record.
CHAR Input-character-default='XXXXXXXX'. Character value in the next
record.
Remarks:
1. Under IOPT = 2, the output matrix data block is actually used as an input and
must be declared APPEND in a FILE DMAP statement.
2. Both inputs must be of the same type matrix.
3. Either IN1 or IN2 may be purged. For IOPT = 2, IN2 must be purged.
4. In matrix appends, string formatted records are copied from one matrix data
block to another.
5. In table appends, the header record is skipped on the appended file and all
remaining records. Also, the trailer of OUT will be set to that of IN2 (IOPT = 1) or
IN1 (IOPT = 2).
6. It is recommended that the OUT data block be a scratch data block. In other
words, it should not be saved on a permanent DBset.
7. For values of IOPT -16, -17, -18, -19, or -2
the order of the parameters written is reversed. For example, IOPT=-20 causes
CHAR to be written first, then NULL2.
8. If NULL1>0, then a type indicator value is written in the word mmediately
preceding the word(s) containing the value of the parameter. The type codes are:
0:INT, 1:REAL, 2:REALD, 3:CMPX, 4:CMPXD and 8:CHAR.
9. For IOPT>9, trailer word 1 will contain a count of the number of data records on
the file and word 2 will contain the value of the NULL1 parameter.
Examples:
1. Generate a matrix [U] whose five columns are a vector {US} multiplied by the
column number.
