Returns a string that is the inverted form of the supplied text.
&INVSTR text
&INVSTR is a built-in function and must be used to the right of an assignment statement.
&INVSTR is used in an assignment statement to reverse the data order. For example, inverting the data 123456 assigns the nominated variable the data 654321.
Operands:
The data to be inverted and placed in the nominated variable. A maximum of data that is specified is the maximum length of the variable. The data is reversed and placed into the target variable of the assignment statement.
Examples: &INVSTR
&A = &INVSTR ABCDEF -* &A will be set to FEDCBA
&1 = &INVSTR &1 &2
Notes:
&INVSTR is a simple way of stripping a number of characters from the end of a variable length string: use &INVSTR to invert the string, then &SUBSTR to strip the required number of characters from the front of the string. A second &INVSTR statement then returns the string to its original order.
&INVSTR is useful when constructing keys for file processing from data entered from a full-screen panel if the data entered must be reordered to construct a suitable key.
