wwUtils::SplitString

Splits a string on CR and LF breaks and a particular width and returns a collection.

This function uses ALINES[] to split breaks, and then falls back to MEMLINES() for lines longer than the specified width (255 by default).

Important for code parsers that rely on strings that don't exceed FoxPro's 255 string literal limit.

lcText = REPLICATE("These are some lines of text, not very long." + CHR(10),3) +;
                   CHR(13) + REPL("Final Return",30)

loLines = SplitString(lcText,255,0,[CHR(13),CHR(10)])  

? loLines.Count   
*** 6 - last line over 255 chars long so breaks

FOR lnX = 1 TO loLines.Count
   ? loLines.Item(lnX)
ENDFOR
o.SplitString(lcString,lnLineLen,lnFlags,lcParseChar)

Return Value

Collection of the string values

Parameters

lcString
Input string

lnLineLen
Max single line length before lines get split with MEMLINES().

lnFlag
Optional - ALINES() flags.

lcParseChar
Optional - Characters to break lines on expressed as a string. Values are used in macro expression to present 1 or more parameters. Leave blank for default (CRLF)

Examples: [chr(13),chr(10)] [",","-",";"] [",",";","-","/"]
