- QUICK REFERENCE
- *INCLUDE FILES*
- --FILENAME----USAGE/INFORMATION-----------------------------------------------
- OPTANSI.H Use in all applications and functions that use OptANSI functions
- Declares macros, prototypes, and some structures
- AUSER.H Use if you prefer to use OptANSI functions as procedures instead
- of functions that return a string, make sure to modify the macro
- aout() to call an output function of your choice
-
-
- *GLOBAL VARIABLES*
- --VARIABLE---TYPE---DESCRIPTION-----------------------------------------------
- acurattr char Current color
- axpos char Current x position on screen
- aypos char Current y position on screen
- ashortcuts char Flags for available ANSI shortcuts/behavior
- astr char15 Buffer area for ANSI result string

- *MACRO VALUES*
- --MACRO--VAL--NOTES-----------------------------------------------------------
- ESC 27
-
- ashotcuts macros
- --MACRO--BIT--RULES-----------------------------------------------------------
- aBKSP 1 True if backspace (char 8, ^H) is nondestructive
- aLF 2 True if linefeed (char 10, ^J) moves cursor down only, if
- false, assumes LF is equivalent to CR/LF combination
- aCR 4 True if carriage return (char 13, ^M) moves the cursor to
- left margin on the same line only
- aCLRSCR 8 True if clear screen (char 12, ^L) clears the entire screen
- to the current color, Telix requires this true
- aRESET 64 True if reset color (ESC[m) resets the color to lightgray on
- black (7), almost always true, QModem might require this true
- aNANSI 128 True if you want to use NANSI or FANSI extensions.
