Special Characters in

Regular Expression

Some fields in Capital Systems Integrator constraints support the use of regular expressions incorporating certain characters that have a special meaning (such as wildcards). If you want to reference one of these characters explicitly (without their special meaning) you must escape the character in those fields with a \ character.

For example:

If you want to specify the value WIRE (+), you must enter it as: WIRE (+)

The special characters to be escaped are:
