INFOR$–Internal Format Table Interface Routines
Parameters
t
Type of call to DUSE$. This parameter is optional and may be omitted. If CB or A is
specified, it must be enclosed by apostrophes.
blank Call the relocatable version of DUSE$. This is the default if t is omitted.
'CB' Call the common bank version of DUSE$.
'A' Call the common bank version of DUSE$ using the Auto Switch
method.
DUSE$
DUSE$ is the function code which specifies which of the INFOR$ routines the
procedure I$NFOR should call. It must be enclosed by apostrophes.
use-name
packet
The use name that is to be attached to the file currently in the ELT$ table. The use
name may be from 1 to 12 characters selected from the set A through Z, 0 through
9, including the special characters - and $. If given as a string, then this parameter
must be surrounded by apostrophes on the procedure call. This parameter may also
be given as the address of a two-word area that contains the name in Fieldata
format, left-justified and space-filled. If the use-name parameter is not specified in
the DUSE$ call, the use name is assumed to be contained by registers A0 and A1.
Address of the 30-word packet required by the common bank version of INFOR$
routine. This parameter is ignored unless parameter t is set to 'A' or 'CB'. If the
common bank version of the INFOR$ routines is being called and this parameter is
omitted, then the routine assumes the address has already been loaded into register
A2 by the calling program.
Return
After the return, register A0 contains the status bits from CSF$ (see the Exec ER
Programming Reference Manual for information). The eight-word area, FILE$, contains
the edited file name, left-justified, and space-filled). If a file name is not specified (FNL =
0), TPF$ is assumed to be the default file.
