Purpose
Used to set system parameters indicating that a select list is active. This information is used by subsequent READNEXT logic.
Arguments
Argument | Input/Output | Value |
CODE | Input | 7 |
| Output | unchanged |
BFS | Input | BFS List |
| Output | unchanged |
HANDLE | Input | file handle |
| Output | unchanged |
NAME | Input | extended selects pass first sort field, otherwise null |
| Output | unchanged |
FMC | Input | null |
| Output | latent index sorts return first sort field, otherwise FMC contains the select pointer |
RECORD | Input | 0 |
| Output | select mode |
STATUS | Input | null |
| Output | returned true by non-index-based selects if the select initialization was successful. Returns null for latent index selects. |
Latent index selects, and argument values associated with these, are a function of SI.MFS, and not of the underlying BFS. For instance, the select mode value of 2 returned in the RECORD argument returns from SI.MFS. To disable a SELECT (cause subsequent READNEXT operations to fall through ELSE branch), RECORD should be set to false.
