```Richard,
These should do the trick!
Here are some Qbasic programs for converting Lat,Lon to and from Locator.
They were copied from text printout in AR magazine or the like.

**************************************************************
PRINT "CONVERTS LOCATOR TO LAT LONG"
INPUT "MAIDENHEAD LOCATOR IN CAPITALS "; A\$
FOR K = 1 TO 6
A(K) = ASC(MID\$(A\$, K, 1))
NEXT K
LO = -180 + (A(1) - 65) * 20 + (A(3) - 48) * 2 + (A(5) - 64.5) / 12
LA = -90 + (A(2) - 65) * 10 + A(4) - 48 + (A(6) - 64.5) / 24
PRINT "MID POINT OF LOCATOR SQUARE"
PRINT "LO "; LO, "LA "; LA
END

*************************************
PRINT "Lat Long to Locator"
PRINT "LAT LON IN DEGREES DECIMAL, SOUTH LAT IS -ve ,WEST LON is -ve"
INPUT "LOngditude,LAtitude"; LO, LA
LO = (LO + 180) / 20
LA = (LA + 90) / 10
A = INT(LO)
B = INT(LA)
LO = (LO - A) * 10
LA = (LA - B) * 10
C = INT(LO)
D = INT(LA)
A\$ = CHR\$(A + 65) + CHR\$(B + 65) + CHR\$(C + 48) + CHR\$(D + 48)
A\$ = A\$ + CHR\$(INT((LO - C) * 24) + 65) + CHR\$(INT((LA - D) * 24) + 65)
END
