Parameter values containing spaces, special characters, and binary values must be used in quotation marks. If a value contains no special characters, then quotes is optional. Runtime Engine supports several quote conventions for representing data:

Single quotes indicate to use the values enclosed in single quotes literally. No escaping is used with single quotes. Single quotes (') are used around text values that include blanks, equal signs (=), or semicolons (;). For example:

Enclose multi-word values (containing spaces or special characters) in quotes, otherwise only the characters prior to the space or special character is used. For example, C:\Program Files\MyData is read as C:\Program unless the string is enclosed in quotes.

Double quotes enable escaping through the use of the backslash (\). For example, if the special character semicolon is a value that is in double quotes, it must be represented as backslash semicolon (\;) so that the Runtime Engine uses the actual value (;).

Sometimes values are already enclosed in double quotes. In this case, the backslash character must be used prior to the special characters. For example:

If the data includes control characters or binary values, double quotes (") must be used. When enclosed by double quotes, the backslash (\) can be used as the escape mechanism. This escaping convention is similar to the one used in the C language. When a backslash appears in the text, it indicates the start of an escape sequence. The following escape sequences are supported:

 

If an option file override string is enclosed in double quotes, then Runtime Engine uses backslash as an escape character. To avoid errors, you can do any of the following:
