AX=8000h"CS_TSR") if BX<>0000h Note: A widely-available copy of ASCII billing itself as "ASCII 2.OO by Nick Zaikin Jr." is in fact a hacked copy of the Compact Soft ASCII v4.23 which is identical except for the changed attribution and version (in fact, some instances of "4.23" were missed); the hacked copy requires the signature string "ASCII 2.OO by Nick Zaikin Jr." instead of the unhacked version's simple signature "ASCII" SeeAlso: AX=8000h"CS_TSR",AX=8002h"CS_TSR" Values for signature strings: "ASCII" ASCII, a popup ASCII table with character input "Halculator" HALC, a 32-bit RPN

function is used to allocate a process handle when the TSR installs itself, by setting ES:DI to point at something other than a CS_TSR process block's signature string and iterating through the possible process handles (0001h to FFFFh) until ES:DI is returned unchanged SeeAlso: AX=8000h"CS_TSR",AX=8001h"CS_TSR",AX=8003h"CS_TSR" --------t-2F8003----------------------------- INT 2F - CS_TSR
