-/*)Module lks19.c
- *
- * The module lks19.c contains the function to
- * output the relocated object code in the
- * Motorola S19 format.
- *
- * lks19.c contains the following function:
- * VOID s19(i)
- *
- * lks19.c contains no local variables.

-/*)S19 Format
- * Record Type Field - This field signifies the start of a
- * record and identifies the the record
- * type as follows:
- *
- * Ascii S1 - Data Record
- * Ascii S9 - End of File Record
- *
- * Record Length Field - This field specifies the record length
- * which includes the address, data, and
- * checksum fields. The 8 bit record
- * length value is converted to two ascii
- * characters, high digit first.
- *
- * Load Address Field - This field consists of the four ascii
- * characters which result from converting
- * the the binary value of the address in
- * which to begin loading this record. The
- * order is as follows:
- *
- * High digit of high byte of address.
- * Low digit of high byte of address.
- * High digit of low byte of address.
- * Low digit of low byte of address.
- *
- * In an End of File record this field con-
- * sists of either four ascii zeros or the
- * program entry address. Currently the
- * entry address option is not supported.
- *
- * Data Field - This field consists of the actual data,
- * converted to two ascii characters, high
- * digit first. There are no data bytes in
- * the End of File record.
- *
- * Checksum Field - The checksum field is the 8 bit binary
- * sum of the record length field, the load
- * address field, and the data field. This
- * sum is then complemented (1's comple-
- * ment) and converted to two ascii
- * characters, high digit first.

-/*)Function s19(i)
- *
- * int i 0 - process data
- * 1 - end of data
- *
- * The function s19() outputs the relocated data

- *
- * local variables:
- * Addr_T chksum byte checksum
- *
- * global variables:
- * int hilo byte order
- * FILE * ofp output file handle
- * int rtcnt count of data words
- * int rtflg[] output the data flag
- * Addr_T rtval[] relocated data
- *
- * functions called:
- * int fprintf() c_library
- *
- * side effects:
- * The data is output to the file defined by ofp.
