AEDIT$–ASCII Image Composition Editing Package<br />

The sequence which must be used when calling the AEDIT$ routines is<br />

A$EDIT pkt . Establish edit mode.<br />

A$Exxxx p1,p2 . Call the AEDIT$ PROCs<br />

. to perform editing.<br />

A$EDITX . Terminate edit mode (A$EPRINT also<br />

. terminates edit mode).<br />

. .<br />

. . Other processing may take place here.<br />

. .<br />

A$EDITR pkt . Re-establish edit mode.<br />

A$Exxxx p1,p2 . Perform more editing.<br />

A$EDITR . Terminate edit mode (or A$EPRINT<br />

. to print line and terminate).<br />

Table 4–1 describes the AEDIT$ routines to initialize and terminate edit mode. Table 4–2<br />

and Table 4–3 describe the routines that may be called in edit mode.<br />

The AEDIT$ PROCs pass parameters in registers A0 and A1. If the parameters are<br />

omitted on the call, then the corresponding load instructions are not generated, and<br />

AEDIT$ assumes the input data is in the designated registers. The parameters may be<br />

in the instruction word format "*u,*x,j"which may be defined with the MASM $EQUF<br />

directive ("label $EQUF *u,*x,*j") and the $EQUF label specified as the parameter.<br />

Parameters are indicated by p1 and p2 in Table 4–1 and Table 4–2.<br />
