Page B-31APPENDIX B SCS/DCA COMMAND SUMMARY
IBMEMUL: Same as IBM, except that the 5250 ALLY will perform
COR even if it has been disallowed with this command.
The 5250 ALLY uses the fc and sd parameters to select a
source paper drawer simply by adding two (2) to the sd
parameter if a forms-type of envelope (fc=02h) is
requested. The 5250 ALLY recognizes up to four source
drawers on the target printer called Paper 1, Paper 2,
Paper 3 and Envelope. On systems that restrict the source
drawer number to less than 3, access to the third and
fourth drawers can be accomplished by selecting a
forms-type of envelope (fc=02h).
The 5250 ALLY will send one of the PFSs 35
PPAPER1, 36 PPAPER2, 37 PPAPER3, 38
PENVEL, 3C LPAPER1, 3D LPAPER2, 3E
LPAPER3, 3F L ENVEL at the beginning of each
page. For target printers that force a page eject when a
paper source is selected, it may be necessary to delete
PFS 07 FF and rely on these PFSs to perform form
feeding. For printers that do not force a page eject when
selecting a source drawer, PFS 07 FF should be left
unmodified (usually containing only 0Ch).
Although source drawer 4 is called Envelope, there is no
reason that this drawer needs to contain envelopes.
Similarly, there is no reason that Paper 1, Paper 2 and
Paper 3 need to hold paper.
PFS 43 JOGOUT is sent to the target printer by the
5250 ALLY at the beginning of each page that requires
an output tray offset (jog), either because the do
parameter was non-zero or because the dd parameter was
changed from the last setting.
PFS 43 JOGOUT is also sent to the printer if the Set
Initial Conditions (SIC) command specifies the Data
Processing (DP) initial condition set. This is the same as
the 3812.
The 5250 ALLY supports dd (destination drawer)
parameters of 00h (no change), and the range of 01h
through 03h. One of the PFSs 44 DEST1, 45
DEST2 or 46 DEST3 is sent to the target printer at the
beginning of each page. These PFSs can be used to select
a destination (output) drawer.
