Address of data area for BSP$. This data area requires at least 43 words. A data
area of 56 words is recommended to accommodate future BSP$ expansion. Words
0 and 1 of this data area must contain an internal file name that is in Fieldata, leftjustified,
and space-filled. This data area is referred to as the file control table (FCT)
and must not be modified between calls to BSP$ after it has been initialized by
RFTI$$.
BSP$-int-level
The BSP$ interface level required by the calling program. The following values may
be specified:
0 This is the only value supported prior to SYSLIB 76R1. It allows access to an
existing PF or LPF and allows an empty file to be initialized as a PF or LPF.
1 This value allows access to an existing PF, LPF or LEPF and allows an empty
file to be initialized as a PF, LPF or LEPF. Note that special care must be
taken when processing elements and element text in an LEPF. See sections
5.1.7 and 5.3 for additional information.
2 This value is supported beginning with SYSLIB 76R3. Allows the same file
access and initialization as interface level 1. In addition, returns an indication if
the program file was initialized on this function call.
length-of-FCT
Length in words of the data area provided in register A0.
