<p><b>New page</b></p><div> @GET-ALTERNATIVE-SYSTEM <file name 1>, <file name 2>, <IS RT LOADER IN SEGMENT FILE NO. 0?> [, <file name 3>], <IS ALT. "SPOOLING PROGRAM" IN SEGMENT-FILE NO. 0?> [, <file name 4>]<br />
Load [[SINTRAN]] from a specified area to the image area and start [[SINTRAN]].<br />
; <file name 1> : specifies SINTRAN:DATA or a similar file containing the first part of the operating system. This file must consist of 66 contiguous pages on disk.<br />
; <file name 2> : (default type = DATA) specifies MACM-AREA:DATA or a similar file containing the rest of the [[SINTRAN III]] system except the [[RT loader]]. It must be a contiguous file allocated immediately after <file name 1>.<br />
; <IS RT LOADER IN SEGMENT FILE NO. 0?> : YES = RT loader is take from segment file number 0. <file name 1> and <file name 2> must be SINTRAN:DATA and MACM-AREA:DATA. NO = a new RT loader is loaded from <file name 3> to segment file 0.<br />
; <file name 3> : name of the contiguous file where the RT loader resides. Specified only if previous parameter was no.<br />
; <IS ALT. "SPOOLING PROGRAM" IN SEGMENT-FILE NO. 0?> : YES = start the original system residing in SINTRAN:DATA, MACM-AREA:DATA and SEGFIL0:DATA. NO = another system on SEGFIL0 is loaded. Then the next parameter must be entered.<br />
; <file name 4> : name of the file where the spooling program resides. It must be a 4 page contiguous file. Specified only if the previous parameter was no.<br />
<br />
Rules:<br />
#Permitted only for user SYSTEM.<br />
#The operating system is transferred to the memory image area (on SEGFIL0) and the system is started. Since this is a "cold start" (similar to CTOM2 - )HENT - 22!) all RT programs must be reloaded.<br />
#Subsequent restarts will use the alternative system. To return to the normal system use<br />@GET-ALTERNATIVE-SYSTEM SINTRAN, MACM-AREA, NO,, S-RTLOADER, YES<br />The RT loader must previously have been placed on the file S-RTLOADER:DATA with the command<br />@MAKE-ALTERNATIVE-RT-LOADER S-RTLOADER:DATA<br />
#All files in this command must reside in the same directory as the current system.<br />
