usage: r_vwait opflg eflag ltime Varb [Value Flag]

Wait until the value of the named variable, VARB, satisfies the specified wait condition. The default wait condition is any change in the value of VARB. You can also use a more specific wait condition by specifying the Value and Flag arguments. The wait conditions indicated by the FLAG parameter are:

    FLAG:  0 - wait until VARB equals VALUE
           1 - wait until VARB is greater than VALUE
           2 - wait until VARB is less than VALUE
           3 - wait until a bitwise AND between VARB and VALUE is non-zero
           4 - wait until VARB does not equal VALUE
           5 - wait until (VARB & VALUE) == 0

If the VALUE and FLAG arguments are omitted, R_VWAIT waits until the value of VARB changes.

Note: For comparisons both VARB and VALUE are treated as short integer values; the variables themselves, however, can be either short or long integers.
