<!--
# Column 1: hex opcode
# Column 2: assembler opcode nmonic
# Column 3: assembler output format
# Column 4: assembler comment output format
# Column 5: script function output format
# Column 6: number of data bytes
# Column 7: data types of bytes
# Column 8: number of elements it pops from the stack
# Column 9: number of elements it pushes to the stack
# Column 10: the 'call effect' true false (1/0) if this is a 'call type' opcode
# Column 11: Flags. Each 0/1 reperesents a false/true condition for each of the
# flags listed below:
# Flag 1: Return flag. If true, it signifises that the function this
# opcode is found in, returns a variable on the stack.
# Flag 2: Paren output flag. If true, we output a pair of parenthesis
# around the usecode script output.
# The following flags are specific only to the usecode script output.
# Flag 3: Increment indent. If true, output the opcode, then increment
# the indent level by 1.
# Flag 4: Decrement indent. If true, decrement the indent level by 1,
# then output the opcode.
# Flag 5: Temporarly increment indent. If true, increment the indent
# level by 1, output the opcode, then decrement the indent level
# by 1.
# Flag 6: Temporarly decrement indent. If trye, decrement the indent
# level by 1, output the opcode, then increment the indent level
# by 1.
# DataType Notes:
# long == dataoffset32 == offset32 == 4 bytes
# flag == extoffset == dataoffset == varoffset == offset == short == 2 bytes
# byte == 1 byte
# offset is calculated from the relative offset it
# A "false" value is defined as integer 0, a null string, or an empty array.
# (stateing obvious) Logically a "true" value would be the opposite of this.
# "Truth value"s pushed on the stack are integer 1 for true, and integer 0
# for false.
# REMEMBER: All arrays are indexed with as 1 based rather then 0 based.
# Notes on number of bytes poped/pushed:
# All numbers are the number of bytes poped/pushed from the stack, with the
# exception of 0xFF, which currently means the number of bytes in the first
# opcode parameter (see opcode 0x07). and 0xFE means the second parameter.
# Logic: parameter referenced is abs(0x100 - value)
# NOTE: Description of function appears below the relevant function.

TODO: To be done...
* {varoffset} is the array to loop over.
* {short}(1st) is used to store the "counter".
* {short}(2nd) is used to store the "max" value. Which is the number of elements stored in {varoffset} or 1 if it's a string or integer.
* {offset} is the relative offset to jump to after the loop is completed.

them, first off the stack is the first appended to the end of the array
(ie. the elements were appended originally to the stack in the order 3, 2,
