TrimString
TrimString (str [, simplifyInternalSpaces])
The TrimString function returns a string identical to str except that leading and trailing whitespace characters are removed. The whitespace characters are space, tab, carriage-return and linefeed.
If the optional second parameter is non-zero, then each run of whitespace characters between words in str is "simplified" to a single space character.
The TrimString function was added in Igor Pro 7.00.
Examples
Print TrimString(" spaces at ends ") // Prints "spaces at ends"
Print TrimString(" spaces at ends ", 1) // Prints "spaces at ends"
