Syntax: StrMid"<string>",
n, <storage variable
name> [,<number of characters>]
Function: Copies a specific number of characters of a
string, starting from the

name> [,
n]
Function: Rotates the left side part and right side
part of a string at the
nth character, and assigns the
resulting string to the specified variable.
Description: Rotation is to the left when “
n” is positive,
and to the right when “n” is negative. Omitting “n”
uses a default value of +1.
StrShift Misc - String(2)
Syntax: StrShift"<string>", <storage variable name>
[,
n]
Function: Shifts a string left or right
n characters, and
assigns the resulting string to the specified variable.
Description: Shift is to the left when “
n” is positive,
and to the right when “n” is negative. Omitting “n”

variable name> [,<search start location>]
Function: Searches "<string 1>" starting from the
specified point (
nth character from beginning of
string) to determine if it contains the data specified
by "<string 2>". If the data is found, this command
returns the location of the first character of "<string
2>", starting from the beginning of "<string 1>".
Description: Omitting the start point causes the
search to start from the beginning of "<string 1>".
strToExp( Misc - String(2)

[<statement>] … : Break : Default : [<statement>] … :
SwitchEnd
• <expression 1> through <expression n> should be
expressions that produce real numbers.
Function: Executes one of a series of processes
based on the value of <expression>.
Description:
• This command executes the statement following
the Case expression that matches the Switch
expression.
• If there is no matching Case expression, the
statement following Default is executed. If there
is no Default specified, a non-match jumps to the
statement following SwitchEnd.
• You can use a multi-statement command (:) in place
of the carriage return to separate statements.
• Switch~SwitchEnd can be exited using the Break
command, Return command, or Goto command.
