FLAG PCTECO USAGE
SETTING THE MODE CONTROL FLAGS n^X -- Sets the search mode flag to n. If n is 0 then searches are independent of case if -1 (or anything else) then search text and text buffer must match exactly in searches. Default = 0 nED -- Sets the value of the edit level flag to n.
m,nED -- Resets bits specified by m and sets bits specified by n. BIT 0 DEC 1 HEX $0001 -- If this bit is set then a caret (^) in a search string is just a literal ^. If clear then the caret modifies the following character to be a control character. -- If this bit is set the Y (Yank) command and _ (underscore) command work unconditionally. If clear then behaviour of the Y and _ commands are as follows: If an output file is open and there is text in the buffer, these commands will produce an error message and the command will be aborted leaving the text buffer unchanged. If no output file is open the Y and _ commands work unconditionally. If the text buffer is empty the Y command will work even if an output file is open (HKY will always work (my motto)). The _ command will succeed in bringing one page of text into an empty text buffer but will fail from bringing in successive pages if an output file is open. -- When set TECO will only expand memory on A cmd and not with Y, P or N cmds. Otherwise full memory expansion is in effect. I think this works. In any case the max buffer size is about 32K. -- TECO-8 only. (This is TECO-11) -- Allow failing searches to preserve Dot. -- Enable immediate escape commands. ?NYI. -- Only move dot by one on multiple occurrence searches. It works. -- Automatic refresh inhibit. ?NYI.

nEH
-- Sets the value of the help level flag to n. If n is equal to 1 error messages are output in abbreviated form (?XXX). If n is equal to 2 error messages are output in a form (?XXX Message). If n is equal to 3 error messages are output the same as 2 then the failing command is output up to and including the failing character in the command followed by a ?. Default = 0 (which is the same as 2) Notes: If you set EH to anything else you are on your own. (This seems to work mostly).
EJ nES
-- Don't mess with this. -- Sets the value of the search verification flag to n. If n is equal to 0 nothing is typed out after searches. If n is -1 the current line is typed out when a search is completed (i.e. a V command is done automatically). If n is between 1 and 31 the current line is typed out with a line feed immediately following the position of the pointer to identify its position. If n is between 32 and 126 the current line is type out with the ASCII character corresponding to the value of n immediately following the position of the pointer to identify its position. If more than one line of type-out is desired, the form m*256 + n can be used. The n is the same as above. The m is the number of lines (-1) before and after the found line to view. (Same as mV command). (See the example in the supplied TECO.INI file). The ES flag does not apply to searches executed inside iterations or macros, lines found inside iterations or macros are never typed out. Default = 0 (but is changed by supplied TECO.INI) Notes: If you set ES to anything else you are on your own. (Don't get into the habit of typing Stext$v$$ if this is not 0 else confusion follows).
nET
-- Sets the type out control flag to n.
m,nET -- Resets bits specified by m and sets bits specified by n. BIT 0 DEC 1 HEX $0001 -- Type out in image mode. Setting this bit inhibits all of TECO's type out conversions. All characters output to the terminal exactly as the appear in the buffer or ^A command. Specifically, the changing of control characters to caret/character form is suppressed. Default: reset. 1 2 $0002 -- Scope mode (i.e. <BS> and ^U erase the screen).
Default: set. 2 4 $0004 -- Read lower case. This is pretty useless these days. Default: set. 3 8 $0008 -- Read without echo for ^T commands. This allows data to be read by the ^T command without having the characters echo at the terminal. Default: reset. 4 16 $0010 -- Cancel ^O on typeout. Setting this bit will cancel any outstanding ^O when the next typeout occurs. After TECO has canceled the ^O, it will automatically reset the bit. Default: reset. 5 32 $0020 -- Read with no wait. This enable the ^T command to test to see if a character is available at the keyboard. If a character has been typed ^T returns the value of the character. If no character has been typed ^T immediately returns a value of -1 and execution continues without waiting for the character. Default: reset. 6 64 $0040 -- Detach flag (?NYI). Forced: reset. 7 128 $0080 -- When this bit is set: 1) all informational messages are supressed; 2) any ^C causes the immediate termination of TECO; 3) any error causes the termination of TECO after the error message is printed. Default: set. (which means if there is an error in your TECO.INI file or anywhere else on startup you'll never get the off ground, this gets reset at TECOs prompt (*)) 8 256 $0100 -- Truncate terminal output (?NYI). Forced: reset. 9 512 $0200 -- You have scope and we have "WATCH", this is a readonly bit (?NYI). Forced: reset. 10 1024 $0400 -- Refresh available, this is a read-only bit (?NYI). Forced: reset. 11 2048 $0800 -- Not used by TECO. Forced: reset.

-- If set accent grave is escape surrogate. (this is good since that key is where GOD intended the escape key to be (at least on *my* keyboard), to enter an accent grave into text when this bit is set use 96I$). Default: reset.

-- If this bit is set and a ^C is typed the bit is reset but execution of the current command string is allowed to continue. This allows a TECO macro to detect typed ^C's. Default: reset.
Default = $0086 Notes: TECO will automatically reset (turn off) the following bits in the ET flag on every error: bit 0 (image output), bit 3 (no echo on ^T), bit 4 (cancel ^O), bit 5 (no stall on ^T) and bit 15 (^C trap). Also, TECO always turns off bit 7 (exit on error, etc.) every time it reaches prompt (*) level. nEU -- Sets the value of the upper/lower case flag to n. Default = -1 nEV -- Sets the value of the edit verify flag to n. The edit verify flag's value is decoded just like the ES flag. Just before TECO prints its prompting * the EV flag is checked. If it is non-zero the lines to be viewed are printed on the screen. Default = 0 nEZ -- Sets text mode flag to n.
m,nEZ -- Resets bits specified by m and sets bits specified by n.
