PAGEDYN sets the size of the paged dynamic pool in bytes.

    To set a value for this parameter, use AUTOGEN initially, and
    then monitor the amount of space actually used with the DCL
    command SHOW MEMORY/POOL/FULL.  If your system requires a
    larger value, you can override the AUTOGEN calculated value
    by setting a higher value for MIN_PAGEDYN in MODPARAMS.DAT.

    PAGEDYN has AUTOGEN, FEEDBACK, GEN, and MAJOR attributes.
