2.6.9 System variables and variables for SERUPRO sequence
SERUPRO detection
The SERUPRO sequence can be detected using the following system variables:
$P_ISTEST is TRUE (valid also for program test)
$P_SEARCH is set to 5 (search in extended program test)
$AC_ASUP Bit 20 in system ASUB is set after the search target
is found (SERUPRO operation step 8.)
$P_ISTEST AND (5 == $P_SEARCHL) reliably detects SERUPRO.
$AC_SEARCH is not supplied by the SERUPRO operation.
Note
$P_SEARCHL is set at the beginning of the SERUPRO operation and
reset on RESET. As a result, $P_SEARCHL continues to be set in the SERUPRO ASUB and
in the residual part program and can continue to be evaluated.
In contrast, the $P_ISTEST variable is set only in the SERUPRO operation and is thus
suitable for searchspecific adaptation of programs.
Synchronized action
SERUPRO can be scanned in a synchronized action using system variable
$AC_SERUPRO = TRUE.
