Its `(Ch : CHAR)` overload returns CHAR, following guide section 5.5. Nonletters and embedded NUL bytes are preserved; the source is unchanged. Use ASCII for predictable case conversion. `_EXP_STRING_ASC(S : _EXP_STRING)` returns the unsigned code of the first byte as INTEGER, or 0 for an empty string. Its `(Ch : CHAR)` overload returns the unsigned byte code of Ch. For ASCII characters this is the ASCII code. + +`_EXP_STRING_CHR(Code : INTEGER)` returns a new `_EXP_STRING` containing the low eight bits of Code as one byte. Unlike built-in STRING, `_EXP_STRING` preserves NUL: `_EXP_STRING_CHR(0)` has length 1. |
