String comparisons
Advanced Allocation Management performs string comparisons using the EBCDIC character set. Strings of unequal length are assumed to be padded with blanks.
If a comparison other than EQ or NE is made against a string that contains generic characters such as * or %, the comparison is made only against the character string up to, and including, the character that immediately precedes the generic character. For more information, see Wildcard characters and string comparisons.
