Great, I'll give this a go. Thanks!

I noticed something odd when I was trying to fill an associated array
with these prompt expansions and the behaviour replicates into non-array
variable assignments too. I suspect this is caused by a bug somewhere..

Kind regards,
Mark

typeset -A datetime DATETIME DateTime dATEtIME
datetime=("month"     "${(%):-%D{"%m"}}"
          "day"       "${(%):-%D{"%d"}}"
          "ymdt"      "${(%):-%D{"%y%m%dT%H:%M"}}")

DATETIME=("month"     "${(%):-%D{%m}}"
          "day"       "${(%):-%D{%d}}"
          "ymdt"      "${(%):-%D{%y%m%dT%H:%M}}")

DateTime=("month"     ${(%):-%D{"%m"}}
          "day"       ${(%):-%D{"%d"}}
          "ymdt"      ${(%):-%D{"%y%m%dT%H:%M"}})

dATEtIME=("month"     ${(%):-%D{%m}}
          "day"       ${(%):-%D{%d}}
          "ymdt"      ${(%):-%D{%y%m%dT%H:%M}})


monthday="${(%):-%D{"%m%d"}}"
MONTHDAY="${(%):-%D{%m%d}}"
MonthDay=${(%):-%D{"%m%d"}}
mONTHdAY=${(%):-%D{%m%d}}

for i (${(k)datetime}) echo "datetime[$i]: ${datetime[$i]}"
for i (${(k)DATETIME}) echo "DATETIME[$i]: ${DATETIME[$i]}"
for i (${(k)DateTime}) echo "DateTime[$i]: ${DateTime[$i]}"
for i (${(k)dATEtIME}) echo "dATEtIME[$i]: ${dATEtIME[$i]}"
echo "monthday: $monthday"
echo "MONTHDAY: $MONTHDAY"
echo "MonthDay: $MonthDay"
echo "mONTHdAY: $mONTHdAY"
=====

Output:

datetime[ymdt]: 121126T13:35}
datetime[day]: 26}
datetime[month]: 11}
DATETIME[ymdt]: 121126T13:35}
DATETIME[day]: 26}
DATETIME[month]: 11}

^ notice the } at the end

DateTime[ymdt]: 121126T13:35
DateTime[day]: 26
DateTime[month]: 11
dATEtIME[ymdt]: 121126T13:35
dATEtIME[day]: 26
dATEtIME[month]: 11

^ correct

monthday: 1126}
MONTHDAY: 1126}
MonthDay: 1126
mONTHdAY: 1126

^ same thing for normal variable assignment
