The second method, using two assignment statements, uses two simple variables. The
first assignment statement assigns the name of the subject of a message read by the
MSGREAD verb into the simple variable &A. The second assignment statement uses
&A in an MDO variable to then assign the value of the subject into the simple variable
&B:
&a = &$MSG.SPI.TANDEM.ZEMS_TKN_SUBJECT_MARK
&b = &$MSG.SPI.&a
For example, the value of the subject of a message could be the following:
\SYS1.$SNA05
SPI to MDO Conversion Rule 2g. NonStop NET/MASTER MS converts the values of some
SPI tokens and fields from internal form to external form before being stored in an
MDO variable. Table 11-4 lists the SPI tokens and fields that are converted to external
form. It also lists the Guardian system procedure call used to convert a token to
external form from internal form (and to internal form from external form).
Refer to the Guardian Procedure Calls Reference Manual, Volume 1 and the Guardian
Procedure Calls Reference Manual, Volume 2 for a detailed description of all Guardian
system procedure calls.
