The assembler THRAss11 is part of a 68HC11 simulator called
THRSim11. This assembler has the following differences
with AS11 (the freeware assembler from Motorola):
The THRAss11 assembler does NOT support the following directives or pseudo-ops:
The following pseudo-ops are recognized but ignored on AS11, the THRAss11
assembler generates an error when you use these directives:
Bit manipulation operands are separated by blanks in AS11. In the THRAss11
assembler you can use both blanks or commas.
Labels can contain the character
$ In AS11. THRAss11 generates
an error when you use a
$ within a label.
Labels are case sensitive in AS11. THRAss11 translates all labels to uppercase.
So LABEL and label are two different labels for AS11 but they are the same
