Append database B to a master database A. The parameters are determined by those in A. If B contains a parameter that is not in A, it is ignored. If A contains a parameter that is not in B, then its value is set to NODATA for each record added from B. Only the expressions of A are included. So A is the master database and B is just a set of records that are appended to it.
Suppose we want to add the data in TESCALAD to TESCAL.
TESCAL TESCALAD
SHOT IP TE SHOT VL IP TE
83001 400 2.1 82995 1.3 380 1.8
83002 410 2.2 82996 1.25 375 1.75
83003 450 3.0 82997 1.5 400 2.0
83004 430 2.8
83005 445 2.9
Program <>: APPEND
Master database? TESCAL
Create a new version of TESCAL? Y
Database to append to TESCAL? TESCALAD
TESCALAD appended to TESCAL.
The resulting TESCAL:
SHOT IP TE
83001 400 2.1
83002 410 2.2
83003 450 3.0
83004 430 2.8
83005 445 2.9
82995 380 1.8
82996 375 1.75
82997 400 2.0
If you want to include VL in the master database, add the parameter
VL to TESCAL before appending TESCALAD.
You can easily do this with the EDIT program.
Program <>: EDIT
Database file <TESCAL>? ,
Edit option? AP
Parameter to add? VL ;
Edit option? \G APPEND
Now when TESCALAD is appended to the master database,
VL will have a NODATA value for shots 83001 to 83005. For
shots 82995 to 82997 VL will be set from its value in
TESCALAD.
