With the IBM XL C compiler used to compile SQLite on IBM z/OS mainframe systems, the default C locale is supported by code page IBM-1047. In this code page the code point 0x15 is valid and represents the newline character. In its aiClass[] array, sqlite3.c marks code point 0x15 as invalid (0x28 - CC_ILLEGAL). This causes SQLite on z/OS to reject valid multi line SQL statements. I would like to propose the below tiny change, only affecting the EBCDIC implementation, which marks code point 0x15 as valid (CC_SPACE - 0x07) and fixes the problem. The diff is against v3.35.2. --- sqlite3.c.original 2021-03-18 19:27:49.040156985 +0100 +++ sqlite3.c 2021-03-18 19:27:41.876206726 +0100 @@ -162308,7 +162308,7 @@ #ifdef SQLITE_EBCDIC /* x0 x1 x2 x3 x4 x5 x6 x7 x8 x9 xa xb xc xd xe xf */ /* 0x */ 29, 28, 28, 28, 28, 7, 28, 28, 28, 28, 28, 28, 7, 7, 28, 28, -/* 1x */ 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, +/* 1x */ 28, 28, 28, 28, 28, 7, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, /* 2x */ 28, 28, 28, 28, 28, 7, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, /* 3x */ 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, /* 4x */ 7, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 26, 12, 17, 20, 10, Thank you, mario
