Outputs a representation of the procedure
procname in which formatting information is preserved.
If the procedure was defined with TO, EDIT, or LOAD, then the output is a list of words.
Each word represents one entire line of the definition in the form output by READWORD, including extra spaces and continuation lines.
The last item of the output represents the END line.
If the procedure was defined with DEFINE, then the output is a list of lists.
If these lists are printed, one per line, the result looks like a definition using TO.
Note: the output from FULLTEXT is not suitable for use as input to DEFINE!
DEFINE "ABC [[a b] [PRINT :a] [PRINT :b]] ABC "Hello "ByeHello Bye
SHOW FULLTEXT "ABC[[to ABC :a :b] [PRINT :a] [PRINT :b] end]
