Change wait time for “File in use” errors

To accommodate system events that may periodically access your files (such as virus scanners), OPEN, DELET, and RENAM will attempt to retry file access for up to 5 seconds before reporting that a file is in use. The RETRYTIME environment variable changes the amount of time they will retry.


The number of 1/10ths of a second to retry. The default is 50 (which is 5 seconds).


Because a virus scanner can take several seconds to scan a file, which sometimes causes a “File in use by another user” error ($ERR_FINUSE), the OPEN statement and the DELET and RENAM routines will by default retry for up to 5 seconds (50 one-tenth-of-a-second retries) before reporting that a file is in use. You can use RETRYTIME to lower the wait time if the operations are taking too long or raise it if you’re still getting unexplained $ERR_FINUSE errors.

Setting location

The environment or the [synergy], [dbr], or [myprog] section of synergy.ini (where myprog is any .dbr file).
