UUDecode

Command group Flag affected Reversible Execute on client Platform(s)
External commands YES NO NO All

Syntax

UUDecode (stream,decoded-streamReturns status

Description

Note: The flag is set according to whether Omnis was able to make a call to this external command.

This Web command is multi-threaded, allowing another thread to execute in the multi-threaded server while it runs. Note that the same socket cannot safely be used concurrently by more than one thread.

UUDecode turns Uuencoded information back into text or binary information. It is the inverse of UUEncode. Uuencoded information is commonly sent over the Internet in a manner that preserves binary information.

Stream is an Omnis Character or Binary field containing the information to UUDecode.

Decoded-Stream is an Omnis Character or Binary field that receives the resulting Uudecoded representation of the Stream argument. Because Uuencoding is generally used for binary information, a Binary field is the norm.

Status is an Omnis Long Integer field which receives the value zero for success, or an error code < 0 for failure. Possible error codes are listed in the Web Command Error Codes Appendix.

Example

; encode the contents of the character variable lString to get lEncodedString
; and decode lEnclodedString to get lString back
Calculate lString as 'This is my character string to encode'
UUEncode (lString,lEncodedString) Returns lErrCode
Calculate lString as ''
UUDecode (lEncodedString,lString) Returns lErrCode
