E$TERM(20)–Terminate
Obsolete Entry Points, PROCs, and Routines
The terminate function returns the routine to the next instruction in machine
language. Upon reentry at point EOUTR$, all counters, modes in effect, interpretive
subroutines, and any partial image are left undisturbed. Control is returned to the
next instruction in machine code. If reentry is made at EOUT$, these are all cleared
and control is returned to the interpretive mode. Entry at EOUT$ is made by:
LMJ X11,EOUTR$
E$LINK(21)–Link
The link function forms subroutines in the editing language. Its effective address
specifies the location of the entry to a subroutine. Subroutines may be nested to a
depth of 10.
E$JUMP(22)–Jump
The jump function with a nonzero effective address causes an interpretive transfer of
control to the designated location. If the address is zero, the jump function serves
as a subroutine exit. Transfer is to the interpretive function following that link control
most recently executed for which no exit has been performed.
E$RPT(23)–Repeat
The repeat function causes the next single interpretive function to be repeated the
number of times specified in the d-field of the repeat word. A repeat function
preceding E$LINK is meaningless; for multiple execution of E$LINK, the routine
EOUT$ should be called within a machine language loop. The t- and m-fields contain
increments to the t- and m-fields of the instruction to be repeated for each
execution. Any modes set by the modal functions which would be in effect for the
first execution of a repeated instruction remain in effect for all executions.
E$CLR(24)–Clear
The clear function sets the image to blanks.
J.3.5. EOUT$–Calling Sequences
This section shows some typing EOUT$ calling sequences. (The FORTRAN formatting
merely indicates the format desired. The I/O functions in FORTRAN use an editing
scheme peculiar to themselves.)
