The full BASIC+ logic to strip the current MFS name from the list, derive the next routine name, and call the next routine looks like this:
| Code Block |
|---|
FS = DELETE(BFS,1,1,1) ; * strip current name NEXT.FS = FS<1,1,1> ; * derive name of next routine * now call next routine. Note that all seven * arguments are passed CALL @NEXT.FS(CODE,FS,HANDLE,NAME,FMC,RECORD, STATUS) |
...
For example, if an MFS called SAMPLE.MFS has been installed onto a Linear Hash file, the BFS argument will be passed to SAMPLE.MFS with this structure:
