[REBOL] Rebol Config/INI File Difficulty Re:(3)

From: agem:crosswinds at: 4-Aug-2000 0:08

very confusing. maybe a bug?! ;-) some while later..

if not, note 'save is paired with 'load .
in the saved file there are no brackets around, as in
   save/header %out.dat sprops []
but after loading you have all in a block again.
so you can do
sprops: LOAD %in.dat

this seems to work ok too:
save/header %out.dat compose/deep [ sprops: [(sprops)] ] []
instead of:
save/header %out.dat compose/deep [ [(sprops)] ] []
evil magic :)

you wanted a "sprops:" in your save for doing, hopefully?

[REBOL [title: "the save/load - demo"]
    pdo: func [a] [print ">>>" probe a print "===" do a]

    write %in.dat {
REBOL []
sprops: [ 1 [ a ] 2 ]
}

    pdo[print read %in.dat]

    pdo [sprops: do %in.dat
        ?? sprops]

    pdo [save/header %out.dat sprops []
        print read %out.dat
        print "---"
        probe load %out.dat
    ]

    pdo [save/header %out.dat compose/deep [sprops: [(sprops)]] []
        print read %out.dat
        print "---"
        probe load %out.dat
    ]
