as one line converts multi-line text into a single line with spaces instead of line breaks. This may be required in expressions and conditions that use other text operations, as these often work on a per-line basis.
For example, in a case in which the attribute ProcedureLog had the value,
prepped draped access completed draped
the condition
ProcedureLog as one line text after “completed” contains “draped”
would be true.
