CHAR: Character from Position in ASCII Character Set

CHAR(i) is the character at the ASCII position i. CHAR also serves to divide a linear string in substrings of equal length in 1 or 2 dimensions.

1. Fortran standard:
   • c1 = CHAR(i) ! c1 is the character in the specified position i of the ASCII table
   Examples:
   • CarriageReturn = CHAR(13) ! or $CR in HicEst ⇾ System Variables
   • LineFeed = CHAR(10) ! or $LF in HicEst
   • CarriageReturnLineFeed = CHAR(13) // CHAR(10) ! or $CRLF in HicEst
   • Tab = CHAR(9) ! or $TAB in HicEst
   • NULL = CHAR(0) !
     null_character
     needed in STRUCT, or DLL
2. HicEst extension:
   • substr = CHAR( substrNR, substrCOUNT, string) ! 1 dimensional
   • substr = CHAR( substrROW, substrCOL, substrROWS, substrCOLS, string) ! 2 dimensional
   • to treat string as an
     array_of_substrings
     with substrCOUNT = substrROWS*substrCOLS elements
   • LEN(substr) is the same as LEN(string) / substrCOUNT
   • Examples:
     • CHARACTER S1 * 16 /'123456789ABCDEF0'/
     • CHAR(3, 4, S1) ! substr(3 of 4 in S1) = '9ABC'
     • CHAR(1, 4, S1) = CHAR(2, 8, S1) ! S1 is now = '34  56789ABCDEF0'
     • CHAR(2,1, 4,2, S1) ! substr(3 of 8) = '56' (stored ROW by ROW)
