Supported integral operations are shown below, and always begin with a percent sign (%).
| Objective | Operators | Examples | Comment |
|---|---|---|---|
| Add, multiply and divide | +*/ |
%i=1+2*4 |
Operands and results are always integers, and any fraction obtained through division is discarded. |
| Make an assignment | = |
%i=1+2 |
This overwrites any earlier assignment. |
| Assign a variable to an integral expression | %variable_name |
%i=3+4+%j |
Legal characters in a variable name are A-Z, a-z, 0-9, and _ (underscore). |
| Measure length | length |
%len=length("H:\MG1655.fasta") print(length($M+$A)) |
If the length argument contains multiple sequences, only the first is used. |
| Count sequences | countSequences |
%s=countSequences("H:\454.fasta") |
Total count across the entire set of sequences provided. |
