Allow MOD directive to accept only the standard base header parameters There are cases where only the standard OS9 module header fields are to be provided. This could be, for instance, in the case of a nonstandard user type module. So allow the execution offset and data size fields to be omitted entirely and handle the module length correctly as well.

>This ASCII format consists of a series of CR+LF terminated "records" of ASCII
text. Each record has the following structure: a start-of-record character
"S", an ASCII record type digit (0-9), a two-digit ASCII hex byte count, a 
four-digit ASCII hex address, an optional sequence of two-digit ASCII hex data
values, and a two-digit ASCII hex checksum. The LW tool chain issues only S0, 
S1, S5 and S9 record types. S1 records are limited to maximum of 16 data bytes
in length, and  paragraph alignment of addresses is favored. The address
sequence of the S-Records directly follows that of the source file; multiple
ORG directives in the source code may result in out-of-sequence addresses in
the S-Record output. </P

>Motorola S-Record format is a standard ASCII format accepted by most memory
device programming equipment. It is particularly useful when the assembled 
code output is destined to reside within an EPROM or Flash memory device,
for example.</P
><P
>LWASM can output this format since version 4.10. LWLINK can output this format
since version 4.11.</P
