MH5ASF30 - MH5ASF30 - Processing of OS/2 Graphics Commands

Description

This include contains handle routines for processing commands
from the Freescope 2/2 OS/2 graphics program. The central routine
is the form 'OS2_HANDLE_COMMANDS', which is called up from
the formpool SAPFH5AO - an application-independent interface with
the graphics program. In this way you can obtain a command
table containing commands and data necessary for processing.
At present three commands are supported:
'//GET': request one or more new structures
'//REF': set up present structure again
'//MIN': process update actions and user menus
The command '//MIN' can contain various sub-commands:
'move': transfer an object
'insert': insert a new or existing object
'terminate': delimit an object
'mode': change an object's staff function and all
self-defined user menus, e.g.
'setdate': set default data for the above sub-commands.
Update actions are carried out as a rule in planning status
2 (planned).
When the commands have been processed control is returned to
SAPFH5AO. The internal table 'OS2_COMMANDTAB' contains
instructions which the graphics program must follow, as well
as supplementary data on objects (command '//MIN'), which
may possibly have been changed, newly set up structure(s)
(commands '//GET' and '//REF'), or appropriate error
messages if an error occurs.
