Re: [Bug 1935037] Re: Invalid charactor in field name

Several calc records allow variable names, like $left, $target, etc.  Transform for sure.

Which CALC allows names? The CALC expressions in calc, calcout, access
security, etc only allow predefined function names and field variables
A,B,C,...

If you have a CALC that allows record names as arguments, quote names
containing special chars.

I do not think that we need to turn records and PVA stucture field names
into C code, do we?
