| 7 | ; THE FIFTH PARAMETER OF SS^BMXADO CONTAINS THE JOIN INSTRUCTIONS
|
|---|
| 8 | ; SYNTAX: DESCENDANT SCHEMA IEN (DETAILS FILE), JOIN FIELD FROM MASTER FILE
|
|---|
| 9 | ; THE FIRST "," PIECE STATES THAT THE MASTER FILE IS JOINED BY ITS .02 FIELD TO THE DETAILS FILE
|
|---|
| 10 | ; THE SECOND "," PIECE STARTES THAT THE DETAILS FILE IS DEFINED BY SCHEMA #6
|
|---|
| 11 | ; AN OPTIONAL 3RD "," PIECE MAY CONTAIN A SECONDARY VSTG TO MORE PRECISELY DEFINE JOIN ITERATION
|
|---|
| 12 | ; E.G., "...~6.,.02,AA~1/1/2004~2/1/2004~~~~~|WT|R"
|
|---|
| 13 | ; IN THIS CASE, THE SECONDARY VSTG SPECIFIES THAT THE AA INDEX BE USED TO CONTROL THE ITERATOR
|
|---|
| 14 | ; THE START AND STOP DATES ARE IN EFFECT BUT MAX IS IGNORED/IRRELEVANT
|
|---|
| 15 | ; THE 1ST "|" PIECE OF THE PARAM SECTION WILL BE AUTOMATICALLY STUFFED WITH PATEINT DFN(S) DURING ITERATION
|
|---|
| 16 | ; IF MULTIPLE JOINS ARE REQUESTED, THEY ARE SPARATED BY THE '@JOIN@' DELIMTER
|
|---|
| 17 | ; "E.G., 6,.02@JOIN@1,.03@JOIN@2,.02@JOIN@9,SUB"
|
|---|
| 18 | ; IN THIS EXAPLE THE MASTER FILE IS JOIND TO THE DETAILS FILES ASSOCIATED WITH SCHEMAS 6, 1, AND 9
|
|---|
| 19 | ; NOTE THAT THE 3RD JOIN DEINED IN THE STRING SPECIFIES A SUBFILE REALTION RATHER THAN A "POINTER" RELATION
|
