There is now only one current increment. This can be modified both with @SET (format 6) and with @PAR INCREMENT. In the past, there were two different increments which were used with different statements even though this was not clearly documented.
A number of statements cause lines to be inserted. If it is not possible to insert a set of lines at an increment of 0.01 then the insert operation is no longer aborted. Instead, EDT attempts the insertion process again down to the smallest possible increment of 0.0001. There was no justification for the abort of the operation in the past.
In the case of statements which write their output to empty (or implicitly deleted) work files, e.g. @COMPARE or @SHOW, line numbers are assigned using the same procedure as for the @COPY statement, i.e., if necessary the increment is reduced and the lines are renumbered in order to permit the output of all the lines. The previous procedure was inconsistent and was therefore confusing.
