[All Platforms] Tokenise (Parse) Command-Line Strings
Posted: Mon Dec 12, 2011 12:24 am
Hey all,
Here's a procedure that will take a CL-style string (delimited by spaces, defining multi-word tokens with quotation marks) and split it into tokens.
Code (Contains usage example)
Hope someone finds it useful 
Thanks

; Description: Procedure that provides a String Tokeniser for Commandlines.
; Author(s): Michael R. King (mrking2910@gmail.com)
; Revision: 1
; Support: Cross-Platform
;
; Notes: Will use spaces as delimiters, and consider strings encapsulated
; by double quotes as a single token.

; - Define our test string -
Define TestString$ = "hello world " + #DQUOTE$ + "this is" + #DQUOTE$ + "a test"
; - Create an Output List -
NewList Output.s()
; - Tokenise the Test String -
CLTok(TestString$, Output())
; - Display results in the Debug Window -
ForEach Output()
Debug Output()
Next
; - Free the List -
FreeList(Output())
End
Thanks
