one.

where:
v string_exp is the string from which you want to extract a substring
v integer_exp1 is the position of the first character in the substring
v integer_exp2 is the desired length of the substring
Example
substring (’abdefg’, 3, 2)
Returns the result: de
Trim-Leading

trim-leading (string_exp)
Example
trim-leading (’ ABC’)
Returns the result: ABC
Trim-Trailing
Returns a string with trailing spaces removed. For example, if you merge two data
items in an expression and the data items have trailing spaces, the spaces between
the data items can be eliminated using the trim-trailing function.
