This is bizarre. I've coded a fair amount of regular expressions and
I've never needed to escape a blank in a regular expression. In fact,
Single UNIX says:
The interpretation of an ordinary character preceded by a
<backslash> ( '\\' ) is undefined,
The z/OS XL C/C++ Runtime Library Reference in the description of
regcmp(), which is described as "withdrawn and are not supported as
part of Single UNIX Specification ..." states:
Note: An non-special character preceded by \ is a one-character
RE which matches the non-special character.
The description of the newer regcomp() makes no such statement.
Is backslash escaping elaborated by ISPF EDIT or by regcomp()?
I have an RCF in requesting a clarification of ISPF's syntax of
delimited strings. My case in point is that with the subject:
My aunt's pen isn't on the table.
The command:
FIND 'aunt's pen'
matches successfully, but the very similar:
FIND 'isn't on'
fails with a syntax error. I can find no explanation of the
difference in current ISPF manuals. I suspect a historical
explanation.
And, in the "CHANGE string1 string2" command, how can I specify
a string2 containing an arbitrary mixture of quotation marks,
apostrophes, and spaces?
Thanks,
gil
