Block Mode Operation
6530 Programmer’s Guide 3-51
Insert Character (Esc O)
The Esc O sequence inserts a blank space at the current buffer address.
This results in moving all subsequent characters in the line (nonprotect
submode) or in the field (protect submode) one position to the right. The
right-most (last) character in the line or field is lost.
In the case of a multiline field in protect submode, the characters wrap
around to the next line. Characters are inserted in unprotected fields only.
If the current buffer address is within a protected field, no insert operation
occurs.
Note In EM3270 mode, this sequence stores a null rather than a
space in the new character position.
Delete Character (Esc P)
The Esc P sequence deletes the character at the current buffer address.
This results in moving all subsequent characters in the line (nonprotect
submode) or in the field (protect submode) one position to the left. The
right-most (last) character position in the line or field is blank filled.
In the case of a multiline field in protect submode, the delete wraps
around from line to line. Characters are deleted from unprotected fields
only. If the buffer address is within a protected field, no delete operation
occurs.
Note In EM3270 mode, this sequence stores a null rather than a
space in the last character position of the field.
Configuration
Values
This group of escape sequences reads or sets values for configuration
parameters. These include parameters for terminal operation if the
workstation or PC and parameters for an attached printer. Each parameter
is specified by a code/value pair, where the code identifies the
configuration item and the value specifies the selection for the item. Table
3-5 on page 3-52 lists the terminal configuration parameters and shows
the code and possible values for each. See Chapter 1 for an explanation of
these parameters.
The Read Terminal Configuration sequence (Esc ?) followed by a set of
code/value pairs causes the 6530 to transmit the current values for the
terminal configuration parameters to the host.
