Method Detail

setTypeAttributes

protected void setTypeAttributes()

Description copied from class: TPFMacroInstructions

This method is used to set some default values in the constructor. A separate method is used for these since the classes inherit the same constructor, but have different default values.

Overrides:

setTypeAttributes in class TPFMacroInstructions

validatePositional

protected int validatePositional(String operand,
                                 int start_position)

When validating position TPFDF macros, the rules are slightly different than when evaluating Assembler and TPF instructions. In TPFDF macros the upper case positional operands can be in any case. For example, if the data file says MYMAC P1,P2,variable,KEY= if it is an Assembler inst: P2,P1,var,KEY= is NOT valid but if it is a TPFDF instruction, P2,P1,var,KEY= is valid.

Overrides:

validatePositional in class AssemblerInstruction

Parameters:

operand - an operand found in the user given operands that needs to be evaluated

start_position - if the operand is a lower case operand, the position will be used to determine where the operand should occur

Returns:

a position: if the operand was a match for an uppercase positional, start_position is returned; if the operand is a match for a lowercase positional operand, the match index is returned; if no match is found, a negative number is returned
