Well, it does interesting things. For example,
/* REXX */
TRACE L
A: DO
SIGNAL S
S: SIGNAL OUT
E: END
OUT: NOP
prints
Ready; T=0.01/0.01 16:47:02
test
3 *-* A:
5 *-* S:
7 *-* OUT:
Ready; T=0.01/0.01 16:47:04
I'm not proposing to emulate this behaviour. ANSI should be enough:
*6.4.2 Trace-only labels*
Instances of LABEL which occur within a grouping_instruction and are not in
a
ncl at the end of thatgrouping_instruction are instances of trace-only
labels
