Using SNA IMF Pass Thru

Appendix F  Differences Between IMF/3000 and SNA IMF/V 

If you are migrating from IMF/3000 to SNA IMF/V on an MPE V system, you
may find the information in this appendix helpful.  IMF/3000 uses either
BSC or SDLC protocol in a Node Type 1 environment.  SNA IMF uses only
SDLC protocol in a Node Type 2 environment. 


NOTE  If you are migrating from IMF/3000 to SNA IMF/V, the following
      IMF/3000 components are not required:  INP download, IMF Monitor,
      Pseudo Driver, and IMF Manager. 


Unlike IMF/3000, which is a complete subsystem that incorporates
functions from the user level down to and including the INP, SNA IMF runs
entirely on the user's stack.  SNA IMF exists once for each user who
invokes the SNA IMF intrinsics.


NOTE  IMF/3000 is currently supported only on MPE V.


This appendix compares and contrasts IMF/3000 with SNA IMF/V in these
areas:

   *   Product structure

   *   Configuration file parameter

   *   Starting Pass Thru

   *   Screen sizes

   *   Display screen ownership
