Nonrepeatable Edit Descriptors
Nonrepeatable Edit Descriptors
The following descriptions show the form, function, and requirements for each of the
nonrepeatable edit descriptors.
Tabulation Descriptors
The tabulation descriptors specify the position at which the next character is
transmitted to or from the buffer. This allows portions of a buffer to be processed in an
order other than strictly left to right, and permits processing of the same portion of a
buffer more than once.
The forms of the tabulation descriptors are as follows (
n is an unsigned integer
constant):
T
n TLn TRn nX
T
n Indicates that the transmission of the next character to or from a buffer is to
occur at the
nth character position. The first character of the buffer is
numbered 1.
TL
n Indicates that the transmission of the next character to or from the buffer is
to occur
n positions to the left of the current position
TR
n Indicates that the transmission of the next character to or from the buffer is
to occur
n positions to the right of the current position
nX Is identical to TRn
Each of these edit descriptors alters the current position but has no other effect.
