SMU Functions
fcbaddress
is a 4-byte integer variable (INTEGER*4).
tdmfilename
If calltype is 0, tdmfilename is a character variable to contain the retrieved
Guardian file name.
If
calltype is 1, tdmfilename is a character value that supplies a Guardian file
name.
The compiler implicitly computes and transmits the size, in bytes, of
tdmfilename
to the function.
filename
If calltype is 0, filename is a character variable to contain the retrieved logical
file name.
If
calltype is 1, filename is ignored.
The compiler implicitly computes and transmits the size, in bytes, of
filename to
the function.
openflag
is a 2-byte integer variable (INTEGER*2).
A file connector has a logical file name and a Guardian file name:
•
The compiler obtains the logical file name of a file connector from the UNIT
directive describing unit
nnn (if specified). Otherwise, the compiler constructs the
logical file name FT
nnn; for example, FT010 is the default logical file name text for
unit 10.
•
The compiler assigns the default Guardian file name of a file connector as
described in the
FORTRAN Reference Manual.
SMU Functions
The SMU functions enable COBOL, FORTRAN, and TAL routines to manipulate saved
ASSIGN, PARAM, and startup messages that are sent to your process when it is
initiated.
All SMU functions are available in the native CRE library. The SMU functions are
described in the following pages, the last of which is followed by COBOL, FORTRAN,
and TAL considerations that apply to all the SMU functions.
