File I/O and IPC Error Codes
This topic describes the error codes that may be returned to the SETTING variable during the execution of a file I/O or interprocess communication (IPC) DataBasic statement.
File I/O Error Codes
After each execution of one of the DataBasic file I/O statements, if the SETTING clause is included, the SETTING variable is assigned a value.
- If the statement executes successfully, the SETTING variable is set to zero (or in some cases a particular value related to statement execution) and the THEN clause of the statement (if any) is executed.
- If execution of the statement fails, the SETTING variable is assigned an error code corresponding to the type of error and the ON ERROR or ELSE clause of the statement (if any) is executed. The tables below specify the possible error codes for a failure in the statements listed.
| Statement Failed | Possible Error Codes | Error Message |
|---|---|---|
| OPEN | 201 4096 |
'file' IS NOT A FILE NAME NETWORK ERROR |
| DELETE | 202 4096 B44 |
'item' NOT ON FILE NETWORK ERROR File has been opened for sequential access |
| RELEASE | 202 4096 B44 |
item' NOT ON FILE NETWORK ERROR File has been opened for sequential access |
| MATREAD, READ, READU, READV, READVU, READNEXT or READPREV | 202 301 4096 B44 |
item' NOT ON FILE READ OPERATION FAILED NETWORK ERROR File has been opened for sequential access |
| MATWRITE, WRITEU, or CLEARFILE | 302 4096 B44 |
UPDATE OPERATION FAILED NETWORK ERROR File has been opened for sequential access |
| WRITEV or WRITEVU | 202 301 302 4096 B44 |
item' NOT ON FILE READ OPERATION FAILED UPDATE OPERATION FAILED NETWORK ERROR File has been opened for sequential access |
IPC Error Codes
If an inter process communication (IPC) statement executes successfully, the SETTING variable is set to zero (or in some cases a particular value related to statement execution) and the THEN clause of the statement (if any) is executed.
If an IPC error is detected while executing an IPC statement, the SETTING variable is set to one of the network error codes listed in the table below.
