  • Rather than using literals, the HCT/HCCT/HFCT DSECTs define many constants which you should use whenever possible. The following are a few examples from the HCT:
    • $ZEROES – doubleword of binary zeroes
    • $F1 – fullword binary one
    • $H4 – halfword binary four
    • $BLANKS – doubleword of EBCDIC blanks (X'40')
