DIM INTEGER Str1(MaxLen/8), Str2(MaxLen/8), Str3(MaxLen/8)

These will contain empty strings when created (ie, their length will be zero). When these variables are passed to the long string functions they should be entered as the variable name followed by empty brackets. For example:

LONGSTRING COPY Str1(), Str2()

Long string variables can be passed as arguments to user defined subroutines and functions. For example:

Sub MySub lstr() AS INTEGER
PRINT "Long string length is" LLEN(lstr())
END SUB

And it could be called like this:

MySub str1()

Sub MySub str1() AS INTEGER
PRINT "Long string length is" LLEN(str1())
END SUB
