Control Characters

Control characters have no meaning in block-mode operation. Instead, use the tilde

character (~) to denote control characters entered from a window sill in block mode.

SeeView transforms characters bracketed with the tilde that are entered from a sill into

the corresponding control character values. For example, if the password for

NULL.NULL is control NOP, enter:

LOGON NULL.NULL,~NOP

Bracketing with the tilde allows you to mix control and normal characters. For example,

to enter the password control N normal OP:

LOGON NULL.NULL,~N~OP

Also, to generate control Y, which signifies an EOF, in response to a prompt:

Be careful when using this feature with the CACHEFILTER OFF option of the ALTER

statement. (See Section 9, SeeView Statements and Script Symbols.) Certain control

characters result in values that are illegal in block mode. These characters might be

placed in the user task cache, and subsequent references to this cache might cause

terminal I/O errors. CACHEFILTER is ON by default and prevents this occurrence.

Use ~RETURN to toggle the BLANKSILL attribute of a window. (See WINDOW on

page 9-119.)

Function Key Summary

Function keys are the primary way to get around the SeeView program. Table 3-1

summarizes the SeeView function key operations for a 6500-series terminal.

Appendix B, SeeView Function Key Reference, has a complete function key reference

for SeeView, including a summary of the function key operations for a PC running a PC

6530 terminal emulator and a detailed description of each function key.
