Code and Display Data or Variable Substitution

The command string can contain variables or symbolics. You can code and display data or variable substitution. Dynamic variable substitution occurs at runtime.

Follow these steps:

1. Code any CA SYSVIEW symbolic value as part of the command string.
2. Insert fields from the selected data row at runtime using specially named variables.

   If a field or column with the name “columnheader” is found on the current screen, the data value for that column or field from the selected row is used to replace the variable.

   Field name coded for substitution:

   &F_columnheader
   

   &FLD_columnheader
   

3. Issue the SYSVIEW VLIST command to view the variables.

   Your variables are displayed for your review.
