[AccessD] formatting strings and placing them in a larger str ing

Cool, now I need to know how to place a string of len N at position O in
another string.

This is for export to a mainframe where the string they want is about 3,000
characters, of which a total of about 200 characters will actually have data
from us.

So:

Insert in a string of blanks (spaces), at position 12, a string of length
10.  REPLACE 10 characters with my 10 characters, starting at position 12.
Insert in a string of blanks, at position 60, a string of length 25.
Insert in a string of blanks, at position 124, a string of length 13.

Etc.

I have a field map of their data, and I can brute force it by just appending
strings together.  I think it was Gustav that suggested a smarter way using
a built in VB function.

I need to take some piece of data, format it correctly (yyyymmdd for
dates, $$$$.CCCC  for currency, XXXX.DD for other floats, etc.

I then need to place it in a specific length field, padded left with
spaces.

I then need to insert that string inside of a larger string at a
specific location.

Someone posted a solution for placing a string inside a larger string
but I can't find the email.

I can build up a string of @ characters into the correct length using a
simple:

    While Len(strPad) < mintLen
        strPad = strPad & "@"
    Wend

But is there any way to just specify that I want a string of 40 @
characters?
