Colors in CL Programs
Are you bored with reading messages in black and white? Try this code to assign colors to message text:
DCL &LIB *CHAR 10
DCL &R *CHAR 1
DCL &Y *CHAR 1
DCL &W *CHAR 1
CHGVAR &R VALUE(X'28') /* Red */
CHGVAR &W VALUE(X'22') /*White */
CHGVAR &Y VALUE(X'33') /*Yellow*/
/* Check if library exists */
IF COND(&LIB = ' ') THEN(GOTO CMDLBL(EOJ))
CHKOBJ QSYS/&LIB *LIB
MONMSG CPF9801 EXEC(DO)
ERR1: SNDUSRMSG MSG(&W||'Library' *BCAT &Y||&LIB *BCAT +
&R||'does not exist')
/* Or display message on Line #24 */
ERR2: SNDPGMMSG MSG(&W||'Library' *BCAT &Y||&LIB *BCAT &R|| +
'does not exist')
ENDDO
EOJ: ENDPGM
Colors in SQL Statements
Table ZD: MAKE(10A), MODEL(10A), MLS1(5 0) , MLS2(5 0) is used in the following examples:
| MAKE | MODEL | MLS1 | MLS2 |
| Toyota | COROLLA | 2 | 8 |
| Nissan | MAXIMA | 3 | 5 |
| Toyota | 4RUNNER | 2 | 5 |
| Ford | F150 | 3 | 3 |
| Toyota | AVALON | 2 | 2 |
Now, add colors via hexadecimal values x'22', x'28', x'38', x'20'. (See the CL Reference Manual for a complete list of hexadecimal values for colors.) In order to concatenate a hexadecimal value to a numeric data column, it must first be converted using the CHAR function.
(CASE when make='Nissan' then x'28'||model
when make='Toyota' then x'38'||model
else x'22'||model end) model, x'22'||CHAR(mls1) mls1, x'20'||CHAR(mls2) mls2
FROM ZD
ORDER BY x'33'||MAKE
You may highlight an entire row for specific selection:
(CASE when make = 'Nissan' then
x'33'||make else make end) make,
model, mls1, mls2 FROM ZD
Note that columns with added hexadecimal characters are shifted to the right.
Assigning colors is useful to set up visual alerts when exceptions occur. For example: values outside of a specified range, or a JOIN statement that does not return data from a joined table, etc.
