compare statement

The compare statement compares two dynamic arrays.

Syntax

compare str.exp1 to str.exp2{present var1} {missing var2}

Parameter(s)


`str.exp1`	String whose elements are to be compared with `str.exp2`.
`str.exp2`	String whose elements are to be compared with `str.exp1`.
present `var1`	At completion, contains a list of elements that exist in `str.exp1` and in `str.exp2`.
missing `var2`	At completion, contains a list of elements that exist in `str.exp1` but do not exist in `str.exp2`.

Description

The compare statement scans through each element in str.exp1 to verify if that element also exists in str.exp2. At completion, var1 contains a list of elements that exist in str.exp1 and in str.exp2. At completion, var2 contains a list of elements that exist in str.exp1 but do not exist in str.exp2.

Example(s)

str1 = "a":@vm:"b":@vm:"c"
str2 = "a":@vm:"d":@vm:"e"
*
compare str1 to str2 present x missing y
print "Result of x = ":x
print "Result of y = ":y

This outputs the following:

Result of x = a
Result of y = b]c
