HP 50g Graphing, 48gII Graphing manual Circ, Cksm, Num, Pos, Repl, Size, Sub, BAUD, PARITY, Transio

The character codes are an extension of ISO 8859/1. Codes 128 through 160 are unique to the calculator. See Appendix J for a complete list of characters and character codes.

The default character ā is supplied for all character codes that are not part of the normal calculator’s display character set.

Character code 0 is used for the special purpose of marking the end of the command line. Attempting to edit a string containing this character causes the error Can't Edit Null Char.

You can use the CHARS application to find the character code for any character used by the calculator. See “Additional Character Set” in Appendix D of the HP 50g User’s Guide.

CIRC
Type:	Command
Description:	Composes two permutations.
Access:	Arithmetic, !ÞPERMUTATION
Input:	Two lists, L1 and L2, representing two permutations. The composition L1○L2 is the permutation
	equivalent to performing permutation L2 first and L1 second.
	Level 2/Argument 1: L1
	Level 1/Argument 2: L2
Output:	A list representing the single equivalent permutation, L = L1○L2
Example:	Compose the permutations given by {3,4,5,2,1} and {2,1,4,3,5}
Command:	CIRC({3,4,5,2,1},{2,1,4,3,5})
Result:	{4,3,2,5,1}

CKSM	Command
Type:
Description:	Checksum Command: Specifies the errordetection sc heme.
	Legal values for nchecksum are as follows:
	•	1digit arithmetic checksum.
	•	2digit arithmetic checksum.
	•	3digit cyclic redundancy check (default).
	The CKSM specified is the errordetection scheme t hat will be requested by KGET, PKT, or
	SEND. If the sender and receiver disagree about the request, however, then a 1digit arithmetic
	checksum will be used.
Access:	…µCKSM
