Good Morning list !

Supposing I get a message whose request header (ISTRH) shows that the RHFI
bit is ON

 BROWSE    SYS1.MACLIB(ISTRH)                         Line 00000069 C
 Command ===>                                                  Scroll
RHFI     EQU   B'00001000'             FORMAT INDICATOR:
*                                      (B) 0=NO FM HEADER, OR
*                                            CHARACTER CODED NETWORK
*                                            SERVICES RU
*                                      (B) 1=FM HEADER INCLUDED, OR
*                                            FIELD FORMATTED NETWORK
*                                            SERVICES RU

If the bit is ON there seems to be 2 possibilities ... An FM header or an
NS RU.
Is there a way to know which one of the cases we are talking about ?

I mean, if I'm interested to obtain from a trace all the FMH-5 related to
the attachment of an LU6.2 transaction, is my only choice to check for
x'0502FF' at the ru+1 ?

I checked the NS RUs and it seems there is none containing the x'0502'
sequence ... Can I trust this forever ?

Thanks in advance for your help. Mauri.
