5.6.2.8 .pskip size[, fill]
 .pspace size[, fill]

Reserve size bytes (including the upper byte). Each byte is filled with the value fill.

This directive is only allowed in a code section. If not in a code section, a warning is generated and the rest of the line is ignored.

The new location counter is relative to the current module and is not an absolute address.

fill is optional. If the value specified for fill is larger than a byte, a warning is displayed and the value is truncated to a byte. If not specified, it defaults to the last .pfillvalue specified.
