TO PROVIDE AN ACCURATE REDISPLAY. ╬OTE, HOWEVER, THAT UNLIKE THE ╚ELP ╙CREENS (SEE BELOW), DISPLAYS ARE NOT SWAPPED ON RETRIEVAL AND THAT A SCREEN OVERWRITTEN BY CALLING THE REDISPLAY IS LOST. ╔TS MOST OBVIOUS VALUE IS STORAGE OF INFORMATION THAT YOU WOULD NEED LATER IN YOU SESSION, INPUT DATA OR LINES OF CODE ╞╥┼┴─ FROM DISK, WITH THE ABILITY TO DIRECTLY ENTER THE LATTER. ╔ FIND THAT ╔ USE IT MORE OFTEN, THOUGH, IN ANOTHER CAPACITY. ╔T (APPARENTLY) PROVIDES A 'LIFTING' OF WINDOWS, BY SIMPLY REWRITING THE SCREEN (SAVED BEFORE THE WINDOW WAS OPENED) SO THAT THE WINDOW SEEMS TO DISSOLVE. ╘HE ═╠╠ CAN BE PORTED TO YOUR OTHER PROGRAMS TO GIVE THEM THAT 'SLICK' LOOK, ONLY PLEASE, GIVE ═R. ├URCIO HIS JUST CREDIT. ╧NE ITEM OF NOTE, THE ROUTINE ASSUMES A ┬┴╬╦15 CONFIGURATION; IT IS ADVISABLE TO ISSUE THAT COMMAND PRIOR TO CALLING THE ╙┘╙, ESPECIALLY IF YOU HAVE BEEN DOING BANK SWITCHING OR IF YOU ARE JUST UNSURE. ╙YNTAX IS AS FOLLOWS: ╙┘╙ 2844,0,0 - WILL SAVE THE CURRENT SCREEN, WITH ALL ╘┴┬ SETTINGS, CURRENT WINDOW, CURSOR POSITION, ETC., IN TACT. ╙┘╙ 2844,0,1 - WILL REDISPLAY THE SCREEN FORMERLY SAVED. ╬OTE THAT ANY NUMBER GREATER THAN 0 WILL WORK FOR REDISPLAY. ┴LSO THE ROUTINE HAS THE ABILITY TO SAVE TWO SETS OF EDITOR VALUES FOR 40- COLUMN WINDOW-SWAPPING (╙┘╙2844,1,X AND ╙┘╙2844,2,X TO IMPLEMENT) BUT IS NOT DISCUSSED HERE SINCE, AS INDICATED BEFORE, THIS IS INTENDED FOR 80-COLUMN FAST MODE. ┬E AWARE THAT, SHOULD YOU CHOOSE TO UTILIZE THESE, THAT THE SAME CAUTIONS AS PREVIOUSLY STATED HOLD TRUE; EXCEPT THAT THEY NOW APPLY TO THE 48 BYTE AREAS AT THE TOP OF THE ┴TTRIBUTES AND THE ╒NUSED AREAS IN ╓─├ MEMORY. ╔F INTERESTED, MORE DETAILED INFORMATION, COMPLETE WITH ╙OURCE CODE, MAY BE OBTAINED IN THE ╞EB 89 ISSUE OF ╘RANSACTOR, ╓OL9, ╔SSUE3. ╙├╥┼┼╬ ╙╫┴╨: ╘HIS FEATURE RETAINS (3) ╚ELP ╙CREENS IN MEMORY, FOR READY REFERENCE. ╘HEY MAY BE ACCESSED AT ANY TIME DURING YOU SESSION BY PRESSING [┼╙├] 1, 2, OR 3; AND YOU RETURN TO YOUR SCREEN, WHEN DONE, BY PRESSING ANY (ACTIVE) KEY. ╘HE ROUTINE SAVES THE CHARACTERS, THEIR ATTRIBUTES AND EDITOR VALUES, SO THAT YOU RETURN TO YOUR SCREEN LIKE YOU NEVER LEFT, LINE LINKS, ETC., IN TACT (NO NEED TO RELIST TO MODIFY THE LINE). ╘HESE COMBINATIONS WOULD NORMALLY YEILD: [┼╙├]-1 : ╘HE REDEFINED ╞UNCTION KEY DEFINITIONS, THE ╙┘╙ COMMANDS FOR THE ╙CREEN-╙AVE/╥EDISPLAY (SEE ABOVE) AND A LISTING OF THE MORE USEFUL ┼SCAPE AND ├ONTROL SEQUENCES.
