jbase - 使用 => 时如何克服 jBase 中的语法错误

问题描述

我有一个使用逻辑表达式的程序，例如 C = (A => B)，但是当我尝试使用 BASIC 编译它时，出现以下错误：

0001 A = 1
0002 B = 2
0003 C = (A => B)


"TEST", 3 (offset 10)  near RESERVED WORD "GT":
C = (A = GT  B)
         ^
        syntax error

1 error was found
jbccom -f -d -aBPX BASIC_91.b failed , command returned a code of 1
jcompile: Returned an error code of 8
 ** Unable to compile source TEST **

我在运行完全相同的环境的不同服务器上拥有相同的程序，即相同的 Linux 版本、相同的 Red Hat 版本、相同的 jBase 版本，并且此代码编译没有问题。

是否存在与一台服务器不同的环境变量或配置项？

jDiag 输出：

            jdiag - jBASE diagnostic '$Revision: 1.15 $'

解决方案

问题围绕 jBase 的版本。jBase 预编译器的这些问题已在 jBase 5.7 及更高版本的更高版本中得到解决。

升级 jBase 版本更正了该问题。
