Writing Programs Using the BASIC Development Language 6-5

Syntax: {$L [labelname]}

Example:

Before translation: After translation:

REM LABEL EXAMPLE 0 REM ...

IF A>C THEN GOTO GET_C_VALUE 10 REM LABEL EXAMPLE

A=55 20 IF A>C THEN GOTO 40

{$L GET_C_VALUE} 30 A=55

C=107 40 C=107

Text

The Text directive allows you to include commands like RUN and LIST in your

program. When translated, these commands are not given line numbers; but they

are included in the output file. As the file is downloaded to the BASIC or

BASIC-T module, these directives are executed as soon as they are encountered.

Syntax:

{$T [command for module]}

Example:

Before translation: After translation:

REM TEXT COMMAND EXAMPLE 0 REM ...

{$I INCLUDE.BDL} 10 REM TEXT COMMAND EXAMPLE

FOREGROUND_BLACK() 20 PRINT CHR(27),“[30m”,

BACKGROUND_RED() 30 PRINT CHR(27),“[41m”,

CLS() 40 PRINT CHR(27),“[2J”,

A=55 50 A=55

C=107 60 C=107

{$T RUN} RUN

In the above example, immediately after the file is downloaded, the RUN

command is encountered and executed.

1 2 ... 72 73 74 75 76 77 78 79 80 81 82 ... 143 144
