Hi Peter,

>If you want to prove that it's easy, you have to do it without a tool like Refox. And a debugger, assembler and APIs are not easy tools for almost all of us.

If you compile this program:

  LOCAL lcName, lcZIP
  ? lcName

you get this FXP code (excerpt starting at position 0x50):

 0x00000050 : 0B 00 AE F7 00 00 07 F7 01 00 FE 0A 00 02 F8 03    ..®÷...÷..þ...ø.
 0x00000060 : 01 F7 00 00 FE 03 00 55 02 00 06 00 4C 43 4E 41    .÷..þ..U....LCNA
 0x00000070 : 4D 45 05 00 4C 43 5A 49 50 B1 00 A1 00 31 00 00    ME..LCZIP±.¡.1..

where the byte code can be interpreted as following (that's my interpretation based on a few variations of the code):

 0B 00     length of first line (11 bytes)
 AE        code for the LOCAL statement
 F7        expression: a variable follows
 00 00     variable #1 (lcName)
 07        comma in list of parameters
 F7        another variable follows
 01 00     variable #2 (lcZIP)
 FE        end of expression

 0A 00     length of second line (10 bytes)
 02 F8 03  code for the ? statement
 01        number of parameters: 1
 F7        expression: a variable follows
 00 00     Variable #1 (lcName)
 FE        end of expression

Not sure if you consider this easy, but all tools you need come with VFP (HexEdit.app).
