field separator as regexp

I have some version of AWK that does not support regular expression field separators ( neither do I have nawk or gawk). How do I go about reading a line with the field separator as either the string "=#" or "+=".

My data looks like this:

abhishek=#nnnnn+#1234+#87


One option is to use tr and change "=" to "+" (I am sure "=" doesnt appear anywhere else), but since the file is rather large,and there are a lot of operations I was planning to do on the fields,while I was reading the file line by line, I would refrain from using it.

Any suggestions please?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
