Abbreviations used:
Function Soft key
FN 9 : IF EQUAL, JUMP
Example FN 9: IF +Q1 EQU +Q3 GOTO LBL "UPCAN25"
If the two values or parameters are equal, jump to the
given label
FN 10 : IF UNEQUAL, JUMP
Example: FN 10: IF +10 NE –Q5 GOTO LBL 10
If the two values or parameters are unequal, jump to
the given label.
FN 11 : IF GREATER THAN, JUMP
Example: FN 11: IF+Q1 GT+10 GOTO LBL 5
If the first value or parameter is greater than the
second, jump to the given label.
FN 12 : IF LESS THAN, JUMP
Example: FN 12: IF+Q5 LT+0 GOTO LBL "ANYNAME"
If the first value or parameter is less than the second,
jump to the given label
IF : If
EQU : Equal
NE : Not equal
GT : Greater than
LT : Less than
GOTO : Go to
