Full Command and Function Reference 3-221
Level 1/Argument 3: The order for the series expansion. The minimum value is 2, and the
maximum value is 20.
Output: Level 2/Item 1: A list containing the limit as a value and as the equivalent expression, an
expression approximating the function near the limit point, and the order of the remainder. These
are expressed in terms of a small parameter h.
Level 1/Item 2: An expression for h in terms of the original variable.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
Example: Obtain the second order Taylor series expansion of ln(x) at x=1.
Command: SERIES(LN(X),1,2)
Result: {{Limit: 0, Equiv: h, Expans: -1/2*h^2+h, Remain: h^3}, h=X- 1}

SERVER
Type: Command
Description: Server Mode Command: Selects Kermit Server mode.
A Kermit server (a Kermit device in Server mode) passively processes requests sent to it by the
local Kermit. The server receives data in response to SEND, transmits data in response to
KGET, terminates Server mode in response to FINISH or LOGOUT, and transmits a directory
listing in response to a generic directory request.
Access: …µ SERVER
Flags: I/O Device (–33), I/O Data Format (–35), RECV Overwrite (–36), I/O Messages (–39), I/O
Device for Wire (–78)
Input/Output: None

SEVAL
Type: Function
Description: Simplifies the given expression. Simplifies the expression except at the highest level, and also
evaluates any existing variables that the expression contains and substitutes these back into the
expression.
Access: Catalog, …µ
Input: Level 1/Argument 1: An algebraic expression.
Output: The expression simplified and with existing variables evaluated.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
Example: With π stored in the variable Y, and the variables X and Z not in the current path, simplify the
following expression. Note that the top-level simplification is not carried out.
Sin(3x – y + 2z – (2x – z)) – Sin(x – 2y + (y + 3z))
Command: SEVAL(SIN(3*X-Y+2*Z-(2*X-Z)) - SIN(X-2*Y+(Y+3*Z))
Result: -SIN(π –(X+3*Z)) -SIN(π –(X+3*Z))
