memclr command

    (A) Function
        Setting the same value in a memory-continued address region.

    (B) Format

        memclr  <memory>  <start>  <end>  <value>

    (C) Parameters
        <memory>
          Designate a facility in which you set a value. 
          The facility type must be memory.

        <start>
        <end>
          Designate a region of memory addresses in which you set a value. 
          The <start> parameter is an unsigned integer. 
          The <end> parameter is a signed integer or an unsigned integer. 
          A signed integer in <end> means the address is a <start> 
          address plus/minus an <end> address. 

        <value>
          Designate a value you want to set. 
          This parameter must be a binary digit string. 
          If the bit width of a facility is not equal to that of a binary 
          digit string, the upper bit of the binary digit string gets 0, 
          or otherwise the upper bit is cut off.

    (D) Notes
        If an SFL memory facility is installed, all the addresses are 
        initialized and then 'u' is put in the every bit.
        For a facility whose type is other than memory, use the set command.

        SFL> memclr memory 30 10 0
        This example sets 0 to the region from the 10th to 30th addresses. 
        It is not allowed to set 0 to the region from the 0th to 10th addresses 
        and the addresses after the 30th.
