| Parameter | Type | Description | |

Description
The routine
PA_Detokenize
allows the 4D Plug-in to retrieve the text of the 4D statement or expression corresponding to the tokenized 4D formula that has been passed.
Before the call, pass the tokenized 4D statement or expression in
tokens
(which the 4D Plug-in obtains using the
PA_Tokenize
) and its length in
len
.
After the call, the routine returns the length of the detokenized text, and the text itself in
text
. You can pass a null pointer to receive the length of the buffer to allocate and then call the function again with the allocated buffer.
Unlike
PA_DetokenizeInTEHandle
which is MacOS or Windows+Mac2Win specific,
PA_Detokenize
allows the developer to manipulate the detokenized text regardless of the platform.
