From: Rick Grevelle <hpcvra!ftg0673%tamsun.tamu.edu> Subject: MDISPN Date: Tue, 16 Jun 92 [Mini-instructions: String on level 2, real number on level 1. (Original used system binary; I changed it). Basically same as DISP except it's twice as fast, and MDISPN doesn't do newlines. -jkh-] Just recently I learned that on the average there was a 30% speed penalty in run time due to the page switching in the 48. According to Jake Schwartz it was Hewlett-Packard's Dennis York who alluded to this during the 1992 Handheld User's Conference in Philadelphia. After the experience gained from developing the machine language library builder, I began looking for ways to greatly increase its performance along with other previously written programs. It'll probably come as no surprise, but I fully expect USRLB for the 48 to build some libraries 10 times faster than's now possible. In similar fashion MDISP has been rewritten, and the speed gained is quite enough to make mention of it. While the routine itself is not very large, and could be even shorter at the expense of speed which is usually the case, it's the font table that accounts for the majority of the bytes; 2040 to be exact. The main advantages are of course the speed gained from not having to bank shift the machine each time the font table is accessed, and the flexibility to create or modify existing fonts. In this current version the first 32 fonts not included in the 48's table have been added and were modeled after the ANSI standard used by MS-DOS. Anyone who plans to write and market software for the 48 should consider the advantage of using a customized display routine for applications requiring a great deal of displaying. As is evident from the source code, MDISPN can be easily modified from its present form to meet a variety of needs, and as previously stated it can just as easily be made shorter, but at the sacrifice of speed. In most cases this particular font size is prefered which is why it's shown here, but similar schemes can be written utilizing either the smallest or largest fonts. Also of interest is the additional ability to control the menu label area of the display; MDISPN has an 8 level understanding of the display while DISPN has 7, and could be quite helpful for browser formats using the complete screen. The source code is straight forward: ************************************************************************* ** ** Name: MDISPN ** ** Calls: SavPtr, GetPtr. ** ** Entry: D1[A]: XXXXX = address of level 1 system binary; level 2 string. ** ** Exit: D1[A]: XXXXX+10 = address of level three object. ** ** Trashes Registers: A[W], B[A], C[A], D0[A], D1[A], and ST[0,1]. ** ** Stack Levels: 2 ** ** Purpose: ** ** Displays level 2 string in one of 8 display levels as specified by the ** level 1 system binary, where ONE is the top most level of the display, ** and EIGHT is the bottom of the display usually occupied by menu labels. ** ************************************************************************* DoCode EQU #02DCC SavPtr EQU #0679B GetPtr EQU #05143 NIBASC \HPHP48-E\ object
