So each control statement must either be labelled or a comment, since it's
impossible not to use column 1 with RECFM=F.

No, because a bit earlier in the same manual, under the "general coding rules"
we find this:
The control statements are free-form; that is, the operation definer, operands,
and comment field can appear anywhere in a statement, provided they appear in
the proper order and are separated by one or more blank characters. Column 1 of
each control statement must be blank, unless the first field is a label or a
comment statement (see Inserting comment statements).

impossible not to use column 1 with RECFM=F.
I fins scant discussion of colons, such as:
• Continuation Column (72)
Any character other than a blank in this column indicates that the
present statement is continued on the next line. However, as long
as the last character of the operand field on a line is a comma or
semicolon or colon followed by a blank, the program assumes that
the next line is a continuation line. The nonblank character in column
72 is required only when a remark field is to be continued or when
an operand is broken at column 71.
And an example:
*1234567
*23456789012345678901234567890123456789012345678901234567890123456789012
INCLUDE COND=(5,4,CH,EQ,
C'ABCD')
SORT FIELDS=(9,
3,
ZD,
A)
OUTREC FIELDS=(1,27,2X,
FIRST FIELD AND TWO BLANKS
51,2,BI,M11,
60:9,3,ZD,PD) THIRD FIELD
(Garbled by Copy/Paste.) I suspect colon has to do with field specification,
but I can find no unified definition of fields.
