In TK3 sold by Digital Precision there are three commands SARRAY filename,array saves the array to the file SARRAY_O is the same as SARRAY but overwrites an original file LARRAY filename,array loads an array from the file The saved arrays have the following header: Position Item 0 'ATK3' 4 Array type (as in the BASIC name table so $0301 is a string array) 6 Offset to data 8 Number of dimensions 10 Index 1 12 Multiplier 1 14 Index 2 16 Multiplier 2 .. ... Offset Start of data These work in S*BASIC programs but you can't compile them with TURBO.
