Returns a string with leading and trailing blanks removed.
&NBLSTR string
&NBLSTR is a built-in function and must be used to the right of an assignment statement.
User variables may contain leading or trailing blanks entered by an operator during full-screen processing, or from other built-in functions such as &SUBSTR, &ASISTR, and &SETLENG.
&NBLSTR removes any leading and trailing blanks from data and returns this string.
If the data consists entirely of blanks, the target variable is set to null.
Operands:
Data or a variable with data from which both leading and trailing blanks are to be removed.
Examples: &NBLSTR
&CMD = &NBLSTR &COMMAND &1 = &NBLSTR &1
To remove only leading blanks, use the &LBLSTR function. To remove only trailing blanks, use the &TBLSTR function.
