This option changes the default size for a dynamically allocated memory buffer. The buffers are indicated by a one- or two-character abbreviation such as ‘op’. For example, the option ‘-yop200’ allocates 200 units for the ‘op’ buffer.
To query the default allocations, just say ‘-y’.
When FWEB runs out of space, it usually (but not always) issues a message telling one which ‘-y’ command to use in order to increase the allocations. (Someday it will reallocate automatically.) One may wish to add some such options to the .fweb file.
