After revewing the doc I think my example will still work, a search using a wildcard may have limitations, but positioning a table after a scan or displaying only those rows that contain the desired contents can still be obtained, I have developed many ISPF diaplogs using TBSARG - TBSCAN and have had much success scaning a table, then displaying the contents of that row in a panel or using this row for file tailoring
here's the begining of the chapter on TBSARG
2.73 TBSARG--define a search argument
The TBSARG service establishes a search argument for scanning a table by using the TBSCAN or TBDISPL services. When TBSARG is used in conjunction with TBDISPL, the panel definition referred to by the TBDISPL request must contain a specification of ROWS(SCAN) on the )MODEL statement in the panel definition.
The direction of the scan, forward or backward, can be specified. The conditions that terminate the subsequent scan can also be specified.
The search argument is specified in dialog variables that correspond to columns in the table, including key variables. A value of null for one of the dialog variables means that the corresponding table variable is not to be examined during the search. However, the variable will be examined if the NOBSCAN parameter was specified when the variable was defined using the VDEFINE service.
Generally, TBSARG is used before TBSCAN or TBDISPL operations to establish search arguments for these operations. To set up a search argument, set table variables in the function pool to nulls by using TBVCLEAR. Next, set a value in each variable in the function pool that is to be part of the search argument. Then, issue TBSARG to establish this variables as the search argument to be used in subsequently requested TBSCAN or TBDISPL operations.
Use the NAMECOND list to establish search argument conditions. For any table variable that was given a value in the function pool, but is not specified in the NAMECOND list, the default is EQ.
Only extension variables can be included in the search argument. They are included by specifying their names in the name-list parameter. The values of these variables become part of the search argument. A null value in an extension variable is a valid search argument.
