F-Correlative Conversion (F)

The F conversion code allows expressions formed as F-correlatives to be used as conversions. These are provided to ease migration from other systems and their use is not recommended for new developments.

The full format of this conversion code is

F; expression

where

A F-correlative used in a conversion code is executed internally in an interpretive manner whereas an F-correlative in field 8 of a Pick style dictionary record is compiled for optimum performance. The compiled version of the expression is stored in the dictionary in fields 15 onwards though the ED and SED editors will hide it.
