Bugs


The 1.2.10 parser can easily get confused by special characters in your regexp, such as curly braces or the $ anchor. If you suspect that this is the case, put your special characters in a variable as a workaround (ael1 syntax):
what=foo;
dollar=$;
Verbose(${REGEX("^foo$" foo)}); // 1
Verbose(${REGEX("^foo$" ${what})}); // 0
Verbose(${REGEX("^foo${dollar}" ${what})}); // 1

In addition, the comma character will be replaced with a pipe character inside the regular expression as follows:
Verbose(${REGEX("^[0-9]\{10,15\}$" ${telnum})})
will actually be parsed as:
Verbose(${REGEX("^[0-9]\{10|15\}$" ${telnum})})
To correct this, escape the comma as follows:
Verbose(${REGEX("^[0-9]\{10\,15\}$" ${telnum})})
