Full Command and Function Reference 3-31
If # n ≥ # 1000000000000 (base 10), only the 12 most significant decimal digits are preserved in
the resulting mantissa.
Access: …ã B → R ( ãis the right-shift of the 3key).

C$
Type: Command
Description: Counted String Command: Enters C$ on the command line to help with the manual entry of a
string object. Must be followed by a number indicating the number of characters to include in the
strings, or an additional $ to indicate that the rest of the command line is a single string. There
must be exactly one separator character after the second $ and before the body of the string.
If the declared length is greater than the number of characters actually available, the string is
automatically truncated to the correct length.
Access: None. Must be typed in.
Example 1: C$ 3 a"b returns "a"b" on level 1.
Example 2: C$ 3abcdef returns "abc" on level 2 and 'def' on level 1 (assuming def is undefined).
Example 3: C$ $ abcdef returns "abcdef" on level 1.
C2P
Type: Command
Description: Takes a list of cycles as an argument, and returns the equivalent permutation. In other words,
finds a permutation from its cyclical decomposition.
Access: Arithmetic, !Þ PERMUTATION
Input: A list of cycles equivalent to a permutation. For example, the list {1,3,5} defines a cycle C, such
that C(1)=3, C(3)=5 and C(5)=1, while items 2 and 4 are not changed. This could be followed by
{2,4} which defines a cycle C, such that C(2)=4, and C(4)=2.
Output: A list representing the permutation equivalent to the cycles.
Example: Convert the cycles given by {{1,3,5},{2,4}} into a permutation:
Command: C2P({{1,3,5},{2,4}})
Result: {3,4,5,2,1}

CASCFG
Type: Command
Description: Restores the default CAS mode settings. This command is almost equivalent to pressing L
!RESET , then selecting “Reset all” and pressing !!OK! , when the CAS Modes input form is displayed.
The difference is that CASCFG sets the modulus value to 13, whereas “Reset all” sets the
modulus to 3.
