Block Substrings

Substrings can be extracted from Embedded Block values.

^^          is used to get a string at the beginning of the text

$$          is used to get a string at the end of the text

Follow ^^ or $$ by the number of characters.

Use the following syntax to get a substring from the value of an Embedded Block:

{BlockName^^1}             Get the first character of the value of the Block named ‘BlockName’

{BlockName^^3}             Get the first three characters of the value of the Block named ‘BlockName’

{BlockName$$1}             Get the last character of the value of the Block named ‘BlockName’

Note:

1. If :: syntax is used then it should come first, as in {BlockName::1^^1}
2. All PDFLib coding will be stripped; care should be taken especially when changing font name or size inside the block value. An intermediate block might be required to change the coding.

A third separator is also allowed after ^^ or $$. The separator here is dash (-).

{BlockName^^2-3}         Get three characters from the beginning starting from the second character

{BlockName$$5-3}         Get three characters starting from the fifth character from the end

Changing shape is also allowed by adding another dash followed by caps (or c) or small (or s)
