Deleting Environment Information
The following example uses the ALTERPARAMTEXT routine to change a parameter
value:
?GUARDIAN ALTERPARAMTEXT
INTEGER error
CHARACTER*20 oldparam, newparam
READ (9,*) oldparam
READ (*,*) newparam
error = ALTERPARAMTEXT (oldparam, newparam, 0, 5 )
Deleting Environment Information
You can delete stored values and text by using the SMU routines that begin with
DELETE. The following example uses the DELETESTARTUP routine to delete the
entire startup message:
?GUARDIAN DELETESTARTUP
INTEGER error
error = DELETESTARTUP ( '*ALL*', 0)
Saved Messages
The internal data structures of the saved process-creation messages can differ slightly
from the standard FORTRAN data structures. The routines operate mainly on
components, or “portions,” of these saved messages. If a message component is not
suitable, the routine formats it either to or from a specific external representation.
The following sections identify the different portions of saved messages.
The PARAM Message
The PARAM message contains all parameter names and the values associated with
the names. The PARAM message includes:
•
A count of the number of named parameters
•
A list of the named parameters in the following form:
°
Length of name
°
Name
°
Length of value
°
Value
You can use SMU routines to request, modify, or delete parameter names and values.
You cannot determine the number of parameters or the names of the parameters in the
PARAM message.
