<h1 class="topictitle1">Example: Use character strings and variables</h1>
|
||
|
|
<div><p>This example shows how several character variables and character
|
||
|
|
strings can be concatenated to produce a message for a work station operator.</p>
|
||
|
|
<div class="section"><p>The example assumes that the variables &DAYS
|
||
|
|
and &CUSNUM were declared as character variables, not decimal variables.</p>
|
||
|
|
<pre>DCL VAR(&MSG)TYPE(*CHAR) LEN(100)
|
||
|
|
*
|
||
|
|
*
|
||
|
|
CHGVAR &MSG ('Customer' *BCAT &CUSNAMD +
|
||
|
|
*BCAT'Account Number' *BCAT +
|
||
|
|
&CUSNUM *BCAT 'is overdue by' +
|
||
|
|
*BCAT &DAYS *BCAT 'days.') </pre>
|
||
|
|
<p>After the appropriate variables have been substituted, the
|
||
|
|
resulting message might be:</p>
|
||
|
|
<pre>Customer ABC COMPANY Account Number 12345
|
||
|
|
is overdue by 4 days.</pre>
|
||
|
|
<p>If the variables &DAYS and &CUSNUM had been declared
|
||
|
|
as decimal variables, two other CHGVAR commands would have to change the decimal
|
||
|
|
variables to character variables before the concatenation could be performed.
|
||
|
|
If, for example, two character variables named &DAYSALPH and &CUSNUMALPH
|
||
|
|
were also declared in the program, the CHGVAR commands would be:</p>
|
||
|
|
<pre>CHGVAR &DAYSALPH &DAYS
|
||
|
|
|
||
|
|
CHGVAR &CUSNUMALPH &CUSNUM</pre>
|
||
|
|
<p>Then instead of &DAYS and &CUSNUM, the new variables &DAYSALPH
|
||
|
|
and &CUSNUMALPH would be specified in the CHGVAR command used to concatenate
|
||
|
|
all the variables and character strings for &MSG.</p>
