AEDIT$–ASCII Image Composition Editing Package
Table 4–1. AEDIT$: Initialization and Termination Editing Routines
PROC Call Generated
Instructions
A$EDIT p1 LA,XU A0,p1
LMJ X11,AEDIT$
A$EDITR p1 LA,XU A0,p1
LMJ X11,AEDITR$
Description
Initialize and establish edit mode.
p1 is the address of the AEDIT$ packet. If p1 is not specified,
the address of the packet must be in A0. S3 of the first word
of the packet is expected to contain the number of words in the
image area, and H2 of the first word of the packet is expected
to contain the location of the image area. The image is set to
blanks, and edit mode is established. The column pointer is set
to the start of the image. AEDIT$ enters quarter-word mode.
AEDIT$ returns a status code in register A1. If A1 is zero, no
error occurred; if A1 is nonzero, an error occurred and AEDIT$
terminates with an ER ERR$. See Table 4–5 for an explanation
of error status codes.
Reenter edit mode without initializing.
A$EDITX LMJ X11,AEDITX$ Terminate edit mode.
A$EPRINT p1 LA,U A0,p1
LMJ X11,AEPRINT$
If p1 is not specified, the address packet must be in register
A0. Edit mode is reestablished, and the column pointer (saved
by AEDITX$) is restored.
The column pointer is saved in the packet. AEDITX$ returns
with the packet address in A0 and the number of words in the
image in A1.
Print image and leave editing mode (call AEDITX$).
Parameter p1 specifies the line spacing for the image. See the
A$EPRINT description in Table 4–2.
