using both % and ! as delimiters around /-containing strings:</p>

<pre class="moz-quote-pre" wrap="">Hi,
In pipeline stage 'inside' I need to match strings that contain /. I tried using !
and %, but they don't seem to work. What are safe string delimiters to use in a netrexx
pipeline? Can they be any character that does not appear in the string, or are there
restrictions?
Hopefully it works the same way as CMS/TSO Pipelines (from the CMS/TSO Pipelines Author's
Edition 1.1.12):
| delimitedString:
|
| A delimited character string is written between two occurrences of a
| delimiter character, as a hexadecimal literal, or as a binary literal. The
| delimiter cannot be blank and it must not occur within the string. Two a
| adjacent delimiter characters represent the null string. It is suggested
| that a special character be used as the delimiter, but this is not
| enforced. However, it is advisable not to use alphanumeric characters,
| because a future release might add a keyword or a number as a valid option
| to a built-in program where only a delimited string is valid today.
|
| A hexadecimal literal is specified by a leading H or X followed by an even
| number of hexadecimal digits. A binary literal is specified by a leading B
| followed by a string of 0 and 1; the number of binary digits must an
| integral multiple of eight.
|
| The keyword STRING can be used to specify that the delimited string
| contains a string that is terminated by delimiter characters. This acts as
| a placeholder so that any non-blank character can be used as the delimiter
| character. Note that this use of the keyword is in addition to a keyword
| that is recognised by a built-in program. (Thus, split string string xabcx)
|
| Examples:
| /abc/
| ,,
| xf1f2f3
| b11000001
| str xabx
