The command: I S eRE ENS W A P , [ , J , .... exchanges the contents of two blocks, whereas: I S eRE E NCO P Y , [ , J , .... copies the contents of one block into another block. The optional parameter causes the software to copy only 1I64th ofthe block (256 bytes out of 16K). therefore takes values in the range 0 to 63. This mode of operation is useful ifit is required to interleave any other processing with screen moving. A screen-swap can take around 150/300ths of a second (150 TIME-counts). The s required are 1 (the normal screen), and then either 2,3,4, or 5. Copy and swap operations where the source or destination is screen 1, will operate much faster. Be careful of the screen hardware-roll effect, as experienced when dealing with disc screen dumps. It should be arranged that all the screen images are constructed (and viewed) with screen 1 set to the same hardware position. The simplest (default) position is that set by a MOD E command. Try out the screen switching commands .... First, run the BANK MANAGER program from Side 1 of your system discs package by: Then type: RUN "BANKMAN" MOD E 1 Screen clears. Now type: I This is the original screen ISCREENCOPY,3,1 'Send original screen to memory 3 C LS More About the Bank Manager .... Chapter 8 Page 3
Screen clears again. Now type: I This is the intermediate screen ISCREENCOPY,2,1 I Send intermediate screen to memory 2 ISCREENSWAP,2,3 I Exchange memory 2 and memory 3 ISCREENCOPY,1,3 I Restore intermediate screen from memory 3 ISCREENCOPY,1,2 I Restore originaL screen from memory 2 Finally on this subject, the last part of Chapter 9 includes a comprehensive 'Screen Designer' program, which incorporates the screen switching facilities provided by the BANK MANAGER. Part 2: Pseudo-file operation Curses filed again .... When regarded as a RAMdisc, the whole of the second 64K is divided into a'RAMfile' comprising a number of fixed length records. The record length can be between 0 and 255 bytes, although 2 bytes is recommended as the minimum. Once the has been established, each record can be accessed by its . It is perfectly acceptable to write the RAMfile using one record length, and read it back using another. NOTE - The RAMfile must contain only data; there is NO facility for it to contain program instructions. As is common with random access disc filing schemes, there is the concept of 'current record number'. This provides, in effect, a default record number, which is particularly useful when auto-stepping through the RAMfile. The command: I BAN KO PEN, .... sets the fixed length of all records, initialises the current record number to zero, but DOES NOT clear the memory in any way. The command: I BAN KW R I T E , @ , [, ] .... writes the to the RAMfile. Chapter 8 Page 4 More About the Bank Manager ....
