The compare statement compares two dynamic arrays.
compare str.exp1 to str.exp2{present var1} {missing var2}
| 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. |
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.
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
