- * Program.......: VIDPOP.PRG
- * Author........: G. Rothbart, The Research Group with modifications by Ted
- * McClure, WordTech Systems.
- * Function......: Fast Linkage to VIDPOP for the WordTech Compiler, QuickSilver
- * : STRING = SAYWHAT screen name or VIDPOP command
- * Reference.....: SAYWHAT 3.0 Manual, WordTech QuickSilver Manual pp 103-104 on
- * the DOSINT command, DOS Tech Ref Manual on Interrupt 10H.
- *
- * NOTE..........: This is a program that ONLY works with the WordTech
- * compiler, and will NOT run in dBASE by itself! The idea is
- * to replace your VIDPOP calls of the form
- *
- * ?? chr(255)+chr(255)+<screen name or VIDPOP command>/
- *
- * with
- *
- * STRING = '<screen name or VIDPOP command></>'
- * DO VIDPOP
- *
- * For example:
- *
- * STRING = 'TINYSCR/'
- * DO VIDPOP
- *
- *
- AH = 256*14
- AL = 255
- *
- * -- send 2 FF's to Int 10H:
- *
- AXREG = AH + AL
- DOSINT 16,AXREG
- AXREG = AH + AL
- DOSINT 16,AXREG
- *
- * -- send SAYWHAT screen name or VIDPOP command to Int 10H:
- *
- I = 1
- DO WHILE I <= LEN(STRING)
- AL = ASC(SUBSTR(STRING,I,1))
- AXREG = AH + AL
- DOSINT 16,AXREG
- I = I+1
- ENDDO
- *
- * -- Screen is UP!
