This program illustrates use of the #cbas#run_only directive and the argv$ string. Here is an example of a short cbas program that counts and displays any arguments that are passed to it on the command line. You could approximate that behavior with carefully crafted line numbers, but appending is perfect if you use merge to include subroutines implemented with What this means is that merged code will not necessarily be executed when it is merged, which may be unlike the behavior of similar commands in other languages, such as C’s #include or Perl’s In other words, if all the code is unnumbered, merged files are numbered starting at the end of the sequence used for the parent file. Otherwise, merged code is appended to the end of the current file. If you write code using line numbers, be careful to anticipate this, or else lines from the merged file may overwrite lines in the current file. Lines from the merged file are inserted into the current file according to line number. Merge can be used from the Chipmunk Basic command line to combine code from two files, but it can also be used within a program to embed code from another file! This allows code from multiple files to be loaded simultaneously. Unlike the load command, the current program, if any, is not closed before merging. merge STRINGEXPRĬhipmunk Basic has a merge command which loads the specified program file’s lines into memory. You can include code with the merge statement. The memstat function reports the internal state of Chipmunk Basic: >memstat()Ĭhipmunk BASIC v3.6.2(b6) current filename: With fseek you can “fast forward” or “rewind” through a file by an arbitrary number of bytes. This can be used for more “random” file access than is possible with the open "filename" for random as # construct, which is really most useful with a regular record format. I do not think fseek accepts any aditional arguments, such as a “seek set” value indicating where to seek from, so POS is always relative to the beginning of the file. I don’t know if there is a way to determine the total length of a file without reading through it until it hits eof. fseek #FNUM, POSįNUM should be an open file the file position marker is moved to byte number POS (where 0 is the first byte in the file). This statement lets you navigate around an open file. Note: These notes are based on an old version of Chipmunk Basic. Recognizes files, basic keywords, named subroutines and gosub labels.
