Some information on the CCD-Rom.
It extents all models of HP41 but best is a CX or having X-Functions- and Time-Module plus printer and IL.
CAT 0 .. F CAT 0 displays ID/AID of IL-peripherals
ENTER selects C forces Device Clear CAT 1 no new function CAT 2 shows headings only, ENTER opens the functionblock
XEQ executes or programs that function
A assigns that function CAT 3 no new function CAT 4 like EMDIR, but Buffer-, Matrix- and Key-Files are
shown correctly CAT 5 no new function CAT 6 Shows any Key-Assignments but synthetic codes are
shown correctly 'TEXT7' or RCL M
C deletes an assignment CAT 7 calles DIR-function of IL-module CAT 8..F like CAT 2, but beginning with the module
on address 8..F
CAT 8 port 1 lower
CAT 9 port 1 upper
CAT A port 2 lower
CAT B port 2 upper
CAT C port 3 lower
CAT D port 3 upper
CAT E port 4 lower
CAT F port 5 upper
ASN allows decimal/hex input of any possible 2 byte
sequence (144 117 for RCL M) XEQ allows decimal input of any possible 2 byte sequence
direct input of any STACK register function
RCL.e STO.c X .a ... direct upper-/lower-case input to ALPHA includes also
decimal and hex entry!
General functions: B? exists a buffer with this identity (X) CAS clear CCD-autostartbit CLB clear buffer with this identity (X) RNDM get a random number SAS set CCD-autostartbit SEED define a startvalue for RNDM SORT sorts a range of registers (Riii, Rjjj) X=iii,jjj
up/or down includes ALPHA
38 of Array-functions like Advantage-Module
One is build from the other!
Hexfunctions: 1CMP 1's complement mode 2CMP 2's complement mode AND bC? bit clear ? bS? bit set? Cb clear bit NOT OR R rotate right, " S shift right, " Sb set bit UNS unsigned mode WSIZE presets the bitsize for all hex-fns (1..32 bits) XOR
I/O functios ABSP alphabackspace (one character) ACAXY accumulate ALPHA by X and Y ('ALPHA'-> 'ALPHA X')
ALPHA left, X right, total width in Y to printerbuf. ACLX accumulate line by X (aa,bbb) puts bbb count of char
aa into printerbuffer ARCLE ARCL's 10 E3 into ALPHA as 10K
23 E7 230M
2.2 E-9 2.2N ... ARCHLH ARCLS's X as HEX-CHARS into ALPHA depends on
mode and WSIZE ARCLI ARCL's 33.33 into ALPHA as 33 CLA- deletes ALPHA from right to left until a space is
found 'ABCD 123' --> 'ABCD ' F/E sets FIX/ENG-Mode INPT universal input routine prompts ALPHA, allows
input from Riii to Rjjj include range-checking
R000 iii,jjjcc
R001 min-value
R002 max-value PMTA same as PROMPT, AON, STOP, AOFF sequence PMTH prompts ALPHA, asks for a HEX-number, see WSIZE PMTK prompts ALPHA, get only allowed keys, returns it's
position 'Text JN' N returns 2, J returns 1
unallowed chars rejected with a tone, one or more
spaces required before valid keys! PRAXY like ACAXY, but directly printed PRL prints a line of '-' chars VIEWH shows X as HEX (see WSIZE) XTOAH like XTOA, instead of a char a Hex-string is appended
ADV-Functions: A+ increments RAM-address in X (X=RRR,B) one byte A+B address(X) +-bytes(Y) A- decrements (see A+) A-A subtracts X from Y result is bytes DCD decodes X to ALPHA (appends) 14 HEX-digits PC RTN exchanges PC with the first return-address PC>X gets the current PC into X PEEKB gets one BYTE from RAM like RCL IND X PEEKR gets one REGISTER from RAM like RCL IND X PHD Program head, returns the address of the first
instruction not programmable PLNG returns the length of a program in bytes POKEB STO IND Y see PEEKB POKER STO IND Y see PEEKR PPLNG programmable PHD X>PC sets the PC from X X>RTN sets first RTN-address from X XR>RTN sets first RTN-address to any line of a program in a
ROM X=linenumber, Y=kk,ll (XROM-number
XF-Memory-Functions: GETB GET Buffer from X-MEM-file GETK GET Keys from X-MEM-file (deletes any userkeys
before) MRGK MeRGes Keys from X-MEM-file SAVEB SAVE Buffer to X-MEM-file SAVEK SAVE Keys to X-MEM-file SORTFL sorts a file (only up)
Hints: alpha lowercase mode may not work correctly in REV. A
Hope this will help.
