To include com programs into batch files you have to write programs which only uses opcodes in the range 0x20 to 0x7e (without < > | % ^ & " !). Small programs can be directly coded using the processor opcode table. Two examples are ech and myinput:
ech.com is similar to the echo command. It writes the command line after the first " till the penultimate character to stdout (without an trailing CRLF) ech.mac

e (echo) and + (increment)
The increment function increments a decimal number by 1.
example: ube.com +123
will write 124 to stdout (note: no space allowed after + and after the number)
The echo function is similar to the standard echo command. The text after the echo command is written to stdout. No <CR> <LF> is appended. You can output any byte by writing the hex value ($3c for < or $0d for <CR> ...). $t writes the current date in the form yymmdd to stdout. After writing the command line text, echo reads from stdin and writes to stdout until a <CR> or <EOF> is read. This byte transfer from stdin to stdout can be modified by subcommands:
The @ must be the first character in the batch file and there must be no trailing spaces in the first 13 lines.
