Try Try block1 Else block2 EndTry Executes block1 unless an error occurs. Program execution transfers to block2 if an error occurs in block1. System variable errCode contains the error code to allow the program to perform error recovery. For a list of error codes, see "Error codes and messages," page 137. block1 and block2 can be either a single statement or a series of statements separated with the ":" character. Note for entering the example: In the Calculator application @ on the handheld, you can enter multi-line definitions by pressing · instead of at the end of each line. On the computer keyboard, hold down Alt and press Enter. Catalog > Example 2 To see the commands Try, ClrErr, and PassErr in operation, enter the eigenvals() program shown at the right. Run the program by executing each of the following expressions. Note: See also ClrErr, page 17, and PassErr, page 73. Define eigenvals(a,b)=Prgm © Program eigenvals(A,B) displays eigenvalues of A·B Try Disp "A= ",a Disp "B= ",b Disp " " Disp "Eigenvalues of A·B are:",eigVl(a*b) Else If errCode=230 Then Disp "Error: Product of A·B must be a square matrix" ClrErr Else PassErr EndIf EndTry EndPrgm tTest tTest m0,List[,Freq[,Hypoth]] (Data list input) tTest m0,x,sx,n,[Hypoth] (Summary stats input) Performs a hypothesis test for a single unknown population mean m when the population standard deviation s is unknown. A summary of results is stored in the stat.results variable. (See page 97.) Test H0: m = m0, against one of the following: For Ha: m < m0, set Hypoth m0, set Hypoth>0 For information on the effect of empty elements in a list, see "Empty (void) elements" on page 131.
