[gradsusr] Maskout two different fields

[Daniel Nairn]

No I don't think so, what I've done is break down the script (as below)
again and this now actually looks okay

'define cape = capesfc'
'define myhel = HLCY0_1000m'
'define myval = maskout(cape,myhel-100)'
'define myval2 = const(myval, 0, -u)'
'd myval2'

I'm still unsure as to what I'm doing wrong when its all combined into one
line, but at least this appears to be working. Thank you.
