The offered way will allow to reduce the used network traffic. The module is intended for formation of instructions on the basis of two entering lines, for transformation of one line into another with use of a minimum of commands. If necessary it is possible to compress a stream of instructions for most effective utilization of the traffic. The given module works with lines, the volume of a line can be, under the theory, down to 4 Gb, but thus the corresponding equipment is necessary. The given module (CS_instr.dll) contains two procedures Formation of instructions: procedure CreateInstructions (oldStr, newStr:PChar; InstrFN:PChar;Dev:Char=#32); oldStr - the Old line (of which we shall form new), zero a terminal line. newStr - the New line (into which we should transform an old line), zero a terminal line. InstrFN - the Way to a time file which contains instructions, zero a terminal line. Dev - a symbol-divider which divides lines into words, by default a blank. Realization of instructions: procedure UseInstructions (oldStr, InstrFN:PChar; newStrFN:PChar;Dev:Char=#32); oldStr - the Old line (of which we shall form new), zero a terminal line. InstrFN - the Way to a time file which contains instructions, zero a terminal line. newStrFN - the Way to a time file which contains a new line which has been generated on the basis of entering instructions. Dev - a symbol-divider which divides lines into words, by default a blank. After purchase of a key to a file with the module and Demo the program for demonstration, you can ??????????? the module CS_instr.dll in the projects.
