Hi I am trying read and write information to/from a text file
the text file is “c:\array1.txt” and contains
MainArray = #(“one”,“two”,“three”,“four”)
array1 = #(“a”,“b”,“c”)
array2 = #(“d”,“e”,“f”)
array3 = #(“g”,“h”,“i”)
array4 = #(“j”,“k”,“l”)
eventually both scripts will be combined but for now the first script reads the info
#####################################################
ArrayFile = OpenFile “c:\array1.txt” mode:“r+”
SkipToString ArrayFile "MainArray = #("
MainBegin = FilePos ArrayFile
SkipToString ArrayFile ")"
MainEnd = FilePos ArrayFile - 2
MainList = MainEnd - MainBegin
Seek ArrayFile MainBegin
MainListText = ReadChars ArrayFile MainList errorAtEOF:false
MainArray = FilterString MainListText "\","
GroupArrays = #()
for i in 1 to MainArray.count do
(
num = i as string
skiptostring ArrayFile ("array"+num+" = #(")
GroupBeg = filepos ArrayFile
skiptostring ArrayFile ")"
GroupEnd = filepos ArrayFile - 2
GroupList = GroupEnd - GroupBeg
seek ArrayFile GroupBeg
GroupListText = readchars ArrayFile GroupList errorAtEOF:false
Groupname = filterstring GroupListText "\","
Sort Groupname
GroupArrays[i] = Groupname
seek ArrayFile 0
)
###########################################################
This seems to work fine.
The second script is suppossed to clear the file but does not work correctly.
#######################################################
for i in 1 to MainArray.count do
(
num = i as string
skiptostring ArrayFile ("array"+num+" = #(")
GroupBeg = filepos ArrayFile
skiptostring ArrayFile ")"
GroupEnd = filepos ArrayFile - 2
GroupList = GroupEnd - GroupBeg
seek ArrayFile GroupBeg
For ii in 1 to grouplist do
(
Format " " to:ArrayFile
)
)
######################################################
The result is this
MainArray = #(“one”,“two”,“three”,“four”)
array1 = #( “)
array2 = #(“d”,“e”,“f”)
array3 = #( “)
array4 = #(“j”,“k”,“l”)
I cannot work out why only 2 arrays have been cleared. Does anyone have any ideas?
The way I usually work with filestreams is to get all the info in the file in a string, filter it or do whatever it needs to be done to it, and write it back to the file. I find it much easier to work with array elements than trying to continuously read and write to a file. Or another easy way to deal with textfiles is to work with getinisetting and setinisetting.
I think the ini settings will suit my purpose.
Thanks Anton
