Decompress a longstring with inflate
Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Inflate function is the Inflate function.
This function takes a deflated longstring input and decompresses it using the "inflate" algorithm. The inflate algorithm is described as part of the deflate specification in RFC 1951.
The $Inflate function accepts one argument and returns a longstring result. The argument is the longstring to be decompressed, and it is required.
Syntax
<section begin="syntax" />%LSTRC = $Inflate(%lstr, option) <section end="syntax" />
Usage
- If the input string is not a valid deflated string, the request is cancelled.
- If compression is not enabled for the current run, the request is cancelled.
- The NCMPBUF parameter must be set by User 0 before the $Inflate function can be used. If $Inflate is called with NCMPBUF = 0, the request is cancelled.
- As with any compression scheme, it is possible that a particular string will become longer after compression. This would happen, for example, if a deflated string were passed to $Deflate .
Examples
In the following example, %LSTR is set to the uncompressed version of the given string:
%LSTRC = $Deflate('How much wood could a woodchuck chuck', 'FIXED') %LSTR = $Inflate(%LSTRC)
