                    ERRORS DURING IBM FORMAT


A  format  error  can occur when using AST  SuperSpool  with  IBM 
FORMAT or DISKCOPY.

IBM  FORMAT  command  must  always  reside  in  a  64K  block  of 
contiguous  memory,  otherwise  a format error  can  occur.   The 
SuperSpool's  /U  command could force the FORMAT command  outside 
the 64K boundary.

If the format error occurs, vary the /U command by +/- 3K.

This should clear the problem.
