Transkeyer
Descripción del contenido de la página
Programa escrito en SBASIC para crear una tabla de teclado de SMSQ/E para un teclado de PC en castellano y juego de caracteres ISO 8859-1.
Para utilizar con la Sinclair QL un juego de caracteres estándar, ISO 8859-1, hacían falta dos cosas: La primera y más sencilla, crear la fuente, para lo que escribí el programa Transfonter; la segunda, crear la tabla de teclado para el sistema operativo SMSQ/E, para lo que escribí Transkeyer (y qxl_kbt_to_data).
El intento de crear una tabla de teclado utilizable fracasó por algo que desde el principio sospechaba: los caracteres de control especiales (por encima del código 191) que la QL usa durante la entrada de textos hacen imposible asociarlos a caracteres normales. Un ejemplo: La letra «Á» («A» con tilde aguda) tiene el código 193 en ISO 8859-1; ese código para la QL es un carácter de control que lleva el cursor al comienzo de la línea (lo que en la QL se hace con la combinación Alt+Izquierda).
A pesar de ello es posible crear códigos fuente en S*BASIC codificados con ISO 8859-1, usando un editor externo, como por ejemplo Vim, que era el objetivo principal, y ver correctamente en la QL tanto el listado del programa como los textos que el programa imprima en pantalla; para ello basta usar la fuente ISO 8859-1 para QL. Lo que no será posible es editar el programa con el editor incorporado en la QL, ni utilizar las funciones de entrada de texto habituales, como INPUT, pues no habrá relación entre las pulsaciones de teclas y los signos obtenidos cuando estos no sean ASCII. Si el programa necesita recibir entradas con el teclado de caracteres que no sean ASCII, la solución es escribir procedimientos o funciones alternativos para la entrada de textos. En cualquier caso, por supuesto, algunas funciones de S*BASIC relacionadas directamente con el juego de caracteres, como las que pasan de mayúsculas a minúsculas, no funcionarán correctamente y habrá que escribir otras equivalentes.
El programa Transkeyer queda abandonado, pero lo publico por si a alguien se le ocurre alguna solución; aunque temo que no la hay, salvo hacer cambios en el sistema operativo.
