I'm relatively new to Pro*C programming. In the following example:
char name; EXEC SQL SELECT 'John Doe' INTO :name FROM DUAL;
"John Doe" is in positions 0-7, blanks in 8-19, and a null in 20. I would really prefer the null to be in position 8 and I don't care what's after that. I wrote a... (1 Reply)

lex
LEX(1) General Commands Manual LEX(1)NAME
lex - generator of lexical analysis programs
SYNOPSIS
lex [ -tvn ] [ file ... ]
DESCRIPTION
Lex generates programs to be used in simple lexical analysis of text. The input files (standard input default) contain regular expressions
to be searched for and actions written in C to be executed when expressions are found.
A C source program, lex.yy.c is generated. This program, when run, copies unrecognized portions of the input to the output, and executes
the associated C action for each regular expression that is recognized.
The options have the following meanings.
-t Place the result on the standard output instead of in file lex.yy.c.
-v Print a one-line summary of statistics of the generated analyzer.
-n Opposite of -v; -n is default.
EXAMPLES
This program converts upper case to lower, removes blanks at the end of lines, and replaces multiple blanks by single blanks.
%%
[A-Z] putchar(yytext[0]+'a'-'A');
[ ]+$
[ ]+ putchar(' ');
FILES
lex.yy.c
output
/sys/lib/lex/ncform
