; Erase gap test 06.
;
; Test 06: Check that the gap is extended to avoid leaving a half-marker.
;
; Operations:
;   - write   32 byte record "AA"
;   - write 4790 byte record "BB"
;   - write tape mark
;   - write   32 byte record "CC"
;   - rewind
;   - forward space record
;   - write gap
;
; Record "BB" occupies all but two bytes of the nominal gap size.  Writing
; the specified 4800-byte gap would leave half of the 4-byte tape mark, so
; the gap is extended to 4802 bytes and starts with a half-gap.  Record "CC"
; is untouched.
;
; Correct tape:
;   Processing tape file 1
;   Obj 1, position 0, erase gap, length = 4800 (0x12C0)
;   Obj 2, position 4800, record 1, length = 32 (0x20)
;   Obj 3, position 4840, erase gap, length = 4802 (0x12C2)
;   Obj 4, position 9642, record 2, length = 32 (0x20)
;   End of physical tape
