Applying substitutions may be accomplished by using the formatString() built-in function. The formatString() function takes up to seven arguments:
<var> = formatString(<msg>[,<sub_1>][,<sub_2>][,<sub_3>][,<sub_4>][,<sub_5>][,<sub_6>])
The <msg> argument is the string variable which was extracted from a message table. Up to six substitution arguments may be specified.
The example below shows the use of the getExternalString() and formatString() built-in functions.
# message table entry: # message_table MY_TABLE message_code OPER_FAIL_MSG, "Operation &1 failed. Reason: &2" --------------------------------------- // ASL fragment. An attempt to perform some operation failed. // the variable 'operation' holds the name of the operation that // failed, the variable 'reason' indicates the reason for the failure. // // extract the string using the default locale (SM_LOCALE) // format = getExternalString("MY_TABLE","OPER_FAIL_MSG"); // // format the substitutions // output = formatString(format,operation,reason) // // print the resulting string // print(output);
