ERRORS
There are different types of error messages. When errors are encountered during
compilation, compiling is stopped and the offending line is displayed. This is a Compile
Time error. Errors encountered during execution of a program are called Runtime Errors.
COMPILE TIME ERRORS
After typing RUN, ZBASIC compiles the program. If errors are encountered, ZBASIC will
stop compiling and display the error on the screen along with the offending line (when
compiling form disk using RUN "Filename" or RUN*, ZBasic will stop compiling, load the
Source Code, and LIST the line where the error occurred.) The Statement within the line
and the line number will be displayed. The following program would cause ZBASIC to print
an error during compile:
00010
00020
00030
00040
CLS
PRINT "HELLO THERE MR. COMPUTER USER!"
PRINT "I AM A COMPUTER"
Z=Z+1: X=X+Z: PWINTX
RUN
Syntax Error in Stmt 03 at Line 00040
00040 Z=Z+1: X=X=Z: PWINT X
NOTE: The error will be marked in some way depending on the computer system being
used. The error marker indicates the general error location on the line where compilation
stopped. To edit line 40 above type: EDIT 40 (or just comma). Fix the spelling of PRINT.
ZBasic will often display the missing character it expected.
00010 INPUT"Enter a number" A$
RUN
";" expected error in Stmt 01 at line 00010
00010 INPUT"Enter a number"_A$
00010 DIM A(10,10)
00020 A(X)=100
RUN
"," expected error in Stmt 01 at line 00020
00020 A(X_)
