Unlike PL/I, C treats characters and strings differently. C uses apostrophes for character constants, which are limited to single characters, either explicitly or due to a backslash (\) escape sequence. IMHO the message should be an error, not a warning.

I have inherited some C code. str2 = str2 ¦ 'xF0'; str1 = str1 >> 4; str1 = str1 ¦ 'xF0'; These receive CCN4118 Character constant 'xF0' has more than 1 character. Examining the source4 it appears the intent is for 0xF0 1. Why would this be a mere informational message? Seems like it should be a warning. that the sizes do not match. The code generated is * str2 = str2 ¦ 'xF0'; SLR r0,r0 IC r0,str2(,r13,157) O r0,=F'10995440' N r0,=F'255' STC r0,str2(,r13,157) * str1 = str1 >> 4; SLR r0,r0 IC r0,str1(,r13,156) SRA r0,4 N r0,=F'255' STC r0,str1(,r13,156) * str1 = str1 ¦ 'xF0'; SLR r0,r0 IC r0,str1(,r13,156) O r0,=F'10995440' N r0,=F'255' STC r0,str1(,r13,156) 10995440 = x'A7C6F0' = 'xF0' 2. This is very old cold, not compiled for years (decades?). Was there a point in C compiler history where 'this was ever a valid hex constant? -- Binyamin Dissen <[email protected]> http://secure-web.cisco.com/1migAFmtAPN_23mBVeDiu-PcLHoaTptHEV1bWf0n3YrzyB1Uy0SXsBP1uzTX8wSAn4-DPZUsU-_qzT8SbayVXo2EZbCir2Tfx9QeOzjyGxw_g_KYhh7gbCn9B3jeArTzhOtHhMNrYEpB00xRSITNW4msCg3wNr1t0GBMc6ETzt-Rq9aaeg5dp3w0jKXB-WQDy0wImP9zMKRnbxDTa-a3NuFXz-lsDTyVM0EtRRHfFq2VooTQgwfmXKxfcsbSqllRPwI0mX6J2FC7gIcbfAZwSk_dITnjwfrhd_tqE273ycjKnTZg4IEqxV538L06VI4j2BGTO1cT6sxnx88x9prTlyu5FDdfABUBUWFmVFb4ZfNMovnEE60CO7fspZO085ot9gRHJ_JXl_jZfujp1eJgqw7wOdYXTwAdbeb4zk8McOOtT7XeUIkpuoeMyUVFkkmvxfMGFwN9gT_m-VzpP-UA-Jw/http%3A%2F%2Fwww.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
