==== Arrays ==== | |||
Number and string arrays are stored on tape in the same format as in RAM [http://www.worldofspectrum.org/ZXBasicManual/zxmanchap24.html|] except that the very first byte (the name of the array) is absent. The name of the array stored in the second byte of ''Parameter 1'' in header block. | Number and string arrays are stored on tape in the same format as in RAM [http://www.worldofspectrum.org/ZXBasicManual/zxmanchap24.html|] except that the very first byte (the name of the array) is absent.

Note: although the array name is saved, you cannot just ''LOAD "" DATA'', you have to explicitly say where to load: e.g. ''LOAD "" DATA w()'', but you can use any letter regardless of the original name. | Note: although the array name is saved, you cannot just ''LOAD "" DATA'', you have to explicitly say where to load: e.g. ''LOAD "" DATA w()'', but you can use any letter regardless of the original name. | ||
