title k20dsp - Kermit-20 Display Routines ; All display code was removed from k20mit and moved to this module as ; part of Edit 194 to address the issue of a very large single source ; file that unexpectedly began generating MCRNEC errors. ; ; During this time, some code was rewritten to decrease symbol table ; usage, to (hopefully) clean up control flow and provide for ; additional checking and better recovery. Speed ups were not avoided ; where possible, typically space being traded for time. However, ; this was not done at the expense of clarity, maintainability being ; of paramount concern. ; ; The code here should be differentiated from the extensive help text ; which is contained in k20hlp, which is constant, does not change ; during runtime and resides in its own .PSECT. The text here is ; dynamically generated. subttl Preliminaries search monsym,macsym,cmd,k20unv ;[194] cmdacs ;Clean up p1-p4 definitions sall ; Tidy listing .directive flblst ; We don't need to see all the ASCIZ bytes... remark common parsing external data extern pars1 ; Data from first parse. extern pars2 ; Data from second parse. extern pars3 ; Data from third parse. extern pars4 ; Data from fourth parse. extern pars5 ;[41] ... remark for file handling extern filjfn ; JFN of currently open file remark other useful routines and data extern qlog ; Quit logging extern %%jser ; Support for error macros extern %%smsg ; Support for smsg macro extern BOUTI% ;[216] BOUT% Internal extern errptr ; Pointer to error message extern getnti ; Get information about line extern ccon, ccoff ; Handle control-C, if we have it extern crlf ; Carriage return line feed extern crlflf ; As previous, but double line feed extern ttyjfn ; JFN on local terminal extern $priou ; Terminal primary output subttl Various NUL: ASCII strings and lengths .psect text ; Text goes in text psect nulnam: byte (7) "N","U","L",":", .chcrt, .chlfd, .chlfd, .chnul astnul: byte (7) "*","N","U","L",":", .chnul .endps text .psect const ; Read-only constants go in constants psecn nulptr: point 7, nulnam ; Pointer to fixed "NUL:" string -^d8 ; "NUL:" (4) + crlflf (4) nul5: point 7, astnul ; Pointer to fixed "*NUL:" ASCIZ -^d5 ; Length of same .endps const ; End of constants .psect code/ronly ; Don't allow stores subttl Clear Control-O, if set ; Preserves all registers, +1 always ; ; This is concerned about the local controlling terminal, not anything ; remote over a pseudo-terminal, network or (maybe) pipe. clrcno: entry clrcno saveac ; Just don't touch move t1, $PRIOU ; Whatever is best to choose for primary output RFMOD% ; Find out about control-O ifje. r ; Failed?? move t4, t1 ; Save error, just in case setz t2, ; Assume ^O has not been typed move t1, $PRIOU ; Reload JFN or device, just in case endif. txzn t2, tt%osp ; Is Output suppress (^O) on? ret ; No, nothing to do SFMOD% ; Otherwise, turn it off ifje. r ; Failed??
