SHRETRY is used to set DOS lock violation retry variables. This may be
necessary with applications that depend on the operating system to retry
file operations when a "locked" condition exists.

Two parameters are required for SHRETRY: (1) the number of times to try
an operation; and (2) a time delay factor between retrys.

Examples:
SHRETRY 3 1 Two retrys, minimum delay between retrys (default).
SHRETRY 20 2 Nineteen retrys, more delay between retrys.
SHRETRY 1 0 No retrys, no delay.
SHRETRY Displays current settings and help.
