The delete code is a 7-bit (all bits) code which is:
1. Generated by the 1050 system when initiated either
manually or automatically, depending on the opera-
RB 1050 Detailed Information
tion. This code is also transmitted during line-loop
operations.
2. Punched when either the delete button or the cor-
rect button is pressed to initiate a tape deletion for a
home-loop operation.
3. Punched by any receiving 1055 when a line-correc-
tion operation is initiated by a negative LRC com-
pare following a line-loop transmission. The line-cor-
rection special feature must be installed to permit
this operation.
4. Not punched by any receiving 1055 in either a
home-loop or line-loop operation when receiving
from a reader. This code is never punched by any
1057 or 1058.
