ROR, ROR$–Relocatable Output Routine
Error Return
The error return occurs when a nonzero status code is encountered in register A2.
Register A2 contains the status code from ER PFWL$. (See the Exec ER Programming
Reference Manual.)
The calling parameters for SROR$EB differ from SROR$ by the addition of a parameter
that defines the external buffer to be used by ROR$. The length and address of the
buffer are provided by the caller in H1 and H2 of register A1, respectively. All other
parameters for SROR$EB are unchanged. A buffer length of at least 1792 words
(1 track) is recommended.

Parameters
length-of-buffer
The number of words in buffer. Must be a multiple of 112 words (4 sectors).
A minimum buffer length of 1792 words (1 track) is recommended.
address-of-buffer
Address of the buffer in caller's data area.

Error Return
The error return is taken when
• An I/O error occurs; A1 will contain the status.
• An internal inconsistency occurred in ROR; A1 will be zero.
