search & replace in a sting

Since you're using IC613 (from your previous post), you could use the newer "pcre" (Perl Compatible Regular Expression) functions which are more powerful than the older "rex" functions. For example:

pat=pcreCompile("[!\\s]")
string=pcreReplace(pat string "" 0)

The \\s (extra escape needed because the pattern really needs a backslash, but backslash is used in SKILL, so needs to be escaped) means whitespace. So it will match space, tab, etc.

You could also use the older functions:

rexCompile("[! ]")
string=rexReplace(string "" 0)

The PCRE-based functions are really powerful, and so I'd recommend those in general if you don't need to make code also work in IC5141 (which only had the older rex functions)

Regards,

Andrew.

Hello Andrew,

How to remember the pattern, and recall it back in the replacement?

e.g. from "inst1.inst2/inst3/net4<5>#6"

to "inst1.inst2\\/inst3\\/net4\\<5\\>\\#6"

Can I use in this way:

pat=pcreCompile("([/<>#])")
string=pcreReplace(pat string "\\\\$_" 0)    ; How about similar $1 or $_?

Thanks,

Yunqi
