User Written Commands
The SVC Interface,
In addition to communicating with the Display Processor (see Section III,
System Overview), the Editing Command Processor of EDGAR can communi­
cate with a user written program via an SVC. The SVC which has been chosen
for this purpose is X'ED'. A user program which desires to use this svc
should point general purpose register one (1) to a 132 byte data area and
issue the SVC. The data area will be processed by the Editing Command
Processor as a command line. Upon return from the svc, general purpose
register 15 contains a return code as follows:
o -indicating the command executed successfully
-1 -indicating the command executed successfully and producea some
informational data. The data has been placed in the data area
pointed to by general purpose register 1.
1 -indicating that the command cannot currently be accepted.
xxx -a message number corresponding to an EDGAR error message
indicating the unsucessful execution of the command. The error
message has been placed in the data area pointed to by general
purpose register 1.
NOTE: Only programs which have been inv_oked as a result of issuing a CMS command on an EDGAR command line, or programs invoked
from a "DEFAUL Til EXEC, may issue the EDGAR SVC. If the pro­
gram is not invoked in this fashion, a return code of one is re­
turned in OPR 15.
