Writing *BELT Cards in the Format of an Earlier Version of PRIMER

The format of the *BELT cards described below has evolved as PRIMER has developed, and while an older deck will always read into a newer version of PRIMER the opposite is not true: each major revision of PRIMER writes cards which will not read into earlier major versions. For example PRIMER V12 will not read a deck generated by PRIMER V13.

To get round this problem there is a preference which will restrict what is written to the format of an earlier version:

primer*mdumm_keyout_format: V11 | V12 | V13 | V14 | V15 | V16 | V17 | V18 | V19 | V20 | V21 | CURRENT

The default is CURRENT , meaning compatible with the current version of PRIMER , but setting an earlier version, eg V12, will restrict output to that version.

Note: restricting output to an earlier version will almost certainly result in some data being omitted with a consequent loss of information. The detailed listings below state where extra informaton has been added from V12 onwards, so the V11 format should be considered to be "baseline".
