You'll have to contact fpsupport about the crash.

However, since the field assignments are identical except for use(5), why
write everything twice?

Also, what happens if 9="MTSP", but AC is neither "A" or "D"?

Also also, why use "{" to concatenate two literals, rather than simply
make a single literal?

    Then: export ascii use=(RF) f=\n
    Then: use(1)="" ; use(2)=":9:eq:"{AB ; use(3)=":150:eq:Y"
    Then: use(4)=":66:eq:"{@td;

MTSP  If: 9 eq "MTSP"
    Then:
      If: MTSP and AC eq "A"
    Then: use(5) = ":4:eq:JBP"
      If: MTSP and AC eq "D"
    Then: use(5) = ":4:ne:JBP"
      If: not MTSP
    Then: use(5) = ""

    Then: use(6)=":::";use(7)=":::";use(8)=":::";use(9)=":::"
    Then: use(10)=":::";use(11)=":::";use(12)=":::";use(13)=":::";use(14)=""
    Then: close use
