STR_MATCH

Script Function: Compares two strings

Syntax

STR_MATCH (String1, String2[, Wildcard1[, Wildcard2]])

Syntax	Description/Format
String1	Alphanumeric character string which should be compared Format: script literal or script variable
String2	Alphanumeric character string which should be compared Format: script literal or script variable
Wildcard1	Character representing any character Format: script literal or script variable Default: "*"
Wildcard2	Character representing one character Format: script literal or script variable Default: "_"

Return code
"Y" - The two strings are identical "N" - The two strings are not identical

Comments

This script function checks if String2 is identical String1. Upper and lower case are distinguished (case-sensitive).

In String2 wildcard characters may be used to form a comparison pattern. Generally "*" stands for any character and "_" for exactly one.

Other wildcard characters may be used and assigned to Wildcard1 and/or Wildcard2.

As of v11 of the Automation Engine the length of variables was changed.
Thus, if a variable contains a blank, the check for a variable of length 0 will return the value "N", as this example would produce:

:SET &TEST# = GET_VAR(‚VARA.TEST‘,‘KEY_DOES_NOT_EXIST‘)
:SET &TRUE# = STR_MATCH(&TEST#,"")

Examples

The first example shows the output of the result "N" in the activation protocol.

:SET &RET# = STR_MATCH("UserInterface", "User-Interface")
:PRINT &RET#

The second example uses a wildcard character for comparison. The result "Y" is output in the activation protocol.

:SET &RET# = STR_MATCH("UserInterface", "U*I*")
:PRINT &RET#

The third example uses a wildcard character which is explicitly specified. The result "Y" is output in the activation protocol.

:SET &RET# = STR_MATCH("UserInterface", "User#", "#")
:PRINT &RET#

The fourth example also includes a wildcard character. It stands for exactly one character. Therefore, the result is "N".

:SET &RET# = STR_MATCH("UserInterface", "User#",, "#")
:PRINT &RET#
